NCERT TEXTBOOK QUESTIONS SOLVED

1. Explain with examples what historians mean by the integration of cults.
Ans: During the period of the 10th Century to the 17th Century, an important trend noticed in the religious life in India is the worship of God in many forms. Many God and Goddesses appear in the scultures and texts but they are various forms of the original deities only. These original deities are Vishnu, Shiva, and Goddesses Durga, Lakshmi and Parvati.
Historians have noticed the two marked trends in the socio-religious life of those days. The first was dissemination of the Brahminical ideas. The Brahminical texts were reproduced in simple Sanskrit. They were now made available to women and shudras, who did not have access to Brahminical literature by and large. The second was the Brahmins who were working on the beliefs and practices. It was a process of evolution, wherein traditional classical traditions were getting new shapes continuously as they were being impacted by the traditions of common people throughout the land.
Now let us look at the two of the following examples.
1.A very good example of the above description is the temple of Jagannatha at Puri
in Orissa. The temple is of Lord Jagannatha who is another form of Vishnu only. The word Jagannatha means one who owns the world.
2.There were many local gods; their statues were often created by wood and stones by tribals. Even families began to have Kul Devata. The Goddeses were also created in wood and stone. They all were in various forms only often of Vishnu.

2. To what extent do you think the architecture of mosques in the subcontinent reflects a combination of universal ideals and local traditions?
Ans: The architecture of mosques in the subcontinent reflects a combination of universal ideals and local traditions in a significant way. Some architectural features of mosques are universal – such as their orientation towards Mecca, evident in the placement of the mihrab (prayer niche) and the minbar (pulpit). However, there are variations in roofs and building materials. For example, a mosque in Kerala (c. thirteenth century) has the shikhara-like roof. Atiya mosque in Mymensingh district, Bangladesh was built with brick. The Shah Hamadan mosque in Srinagar, on the banks of Jhelum is often regarded as the “jewel in the crown” of all the existing mosques of Kashmir was built in 1395. It ig one of the best examples of Kashmiri wooden architecture. It has the spire and the beautifully carved eaves. It is decorated with papier mache.

3. What were the similarities and differences between the be-shari‘a and ba-shari‘a sufi traditions?
Ans: Shari’a is the Islamic law that is applied in a truly Islamic country. The Shari’a law owes its origin to the Holy book of Quran, Hadis (Law book of Islam) and teachings of Prophet Muhammad.
In the medieval ages the Islamic world witnessed a big social and religious movement called Sufi movement. Sufi movement was the people-centric and not God-centric. It believed serving people was the real form of worship. Sufi movement has had many branches too. One group of Sufi preachers took very radical path. They were mystics who renounced material world took to the life of asceticism. Further they also rejected the supremacy of the Shari’a laws. Such sufis were called be-shari‘a.

On the other hand , there were sufi saints who criticised the extravagant lifestyle of monarchs and Khaliphates but did not reject Shari’a laws. For them Shari’a laws were sacrosant. These Sufi saints have been called be-shari‘a.

4. Discuss the ways in which the Alvars, Nayanars and Virashaivas expressed critiques of the caste system.
Ans: The early Bhakti Movement was led by Alvars and Nayanars. It was the period of the 6th Century. Alvars are those who were disciples of Vishnu and Nayanars were those who claimed themselves the followers of Lord Shiva. They travelled place to place and would sing devotional songs in Tamil in the name of Shiva or Vishnu as the case may be. Apart from being a religious movement, it was a social movement too. Many historians are of the view that Alvars and Nayanars gave a blow to the caste system and Brahminism. This is corroborated by the fact that the movement was open to people from diverse background. The Bhaktas came from the castes of Brahmin to artisans to even those that were considered untouchables.
Virashaivas was a movement of the 12th Century that took place in Karnataka. The movement was led by a Brahmin named Basavanna (1106-68), who was a minister in the court of Chalukya king. The followers of Basavanna are called Virashaivas and they worshipped Shiv. They were also called and perhaps more often Lingayats, which literary means wearer of Lingas. They challenged the caste system and they challenged the idea of any caste being pollutant. This helped them grow support among marginalised sections of the society. Virashaivas also attacked some evil practices
supposedly not approved by Shashtras, such as post puberty marriage and remarriage of widows. Further they also questioned the theory of rebirth.

5. Describe the major teachings of either Kabir or Guru Nanak and the way they have been transmitted. (or)
Explain the teachings of Guru Nanak. Did he want to establish a new religion?
Ans: Kabir is a great poet-cum-saint of Indian society. He has had appeal among Hindus and Muslims alike as it is believed that he was bom as Hindu but was brought up by a muslim couple. He wrote poems that exhorted both communities to take to social reforms.
The major teachings of Kabir were as follows:
1. Kabir described God as nirankar (having no shape). He used the terms drawn from Islamic tradition like Allah, Khuda, Hajrat and Peer but also used words of Vedic traditions like Alakh ( (the unseen) and nirakar ( the formless). Thus, he freely took to both traditions viz. Islamic and Vedantic.
2. He repudiated idol worship and polytheism.
3. He emphasised on the oneness of God though there can be many names of His.
4. He criticised religious rituals of hindus and muslims alike.
5. He also preached against caste discrimination.
6. He combined the Sufi traditions of love of God with the Hindi tradition of remembrance of God.
7. He also emphasised the dignity of labour.
Thus, the essence of the teachings of Kabir was simple living based on love and respect all. He wrote in simple language to be understood by common man of the country.
Guru Nanak and his teachings
Guru Nanak was born in a Hindu family in 1469 at Nankana Saheb on the bank of the river Ravi. His birth place is now in Pakistan. He learnt Persian, Arabic , Hindi and Mathematics. He spent time in the company of Sufi saints and Bhaktas of various socio-religious movements.
The major teachings of Guru Nanak are as follows:
1. He rejected the religious texts of both Hindus and Muslims.
2. He preached God is Nirakar viz. without any shape.
3. He criticised the religious practices like ceremonial bath, sacrifices , idol worship, and emphasised simplicity.
4. He called upon his followers to connect to divine by remembering and repeating the divine name.
Guru Nanak expressed himself in Punjabi, the language of the local people in a lyrical form called Shabad. Shabad can be recited in various ragas.

6. Discuss the major beliefs and practices that characterised Sufism.
Ans: The major beliefs and practices that characterised Sufism are as given below –

  1. Sufis turned to asceticism and mysticism in protest against the growing materialism of the Caliphate as a religious and political institution.
  2. They were against the dogmatic definitions and scholastic methods of interpreting the Qur’an and sunna adopted by theologians.
  3. They laid emphasis on seeking salvation through intense devotion and love for God.
  4. They regarded Prophet Muhammad as a perfect human being and suggested to follow his example.
  5. Sufis organised communities around the khanqah controlled by a shaikh, pir or murshid.
  6. Special rituals of initiation were developed in which initiates took an oath of allegiance, wore a patched garment and shaved their hair.
  7. After the death of the shaikh, his tomb-shrine or dargah became the centre of devotion for his followers who performed pilgrimage or ziyarat to his grave on the occasion of death anniversary or urs.

7. Examine how and why rulers tried to establish connections with the traditions of the Nayanars and the sufis.
Ans: Nayanars were the worshippers of Lord Shiva. It gained a shape of powerful Bhakti movement in South India in 6th Century onwards. Apart from being popular with the people, the movement got support and patronage of the rulers of the time. This is manifested by the following facts:
1. A major part of South India was ruled by Chola Kings during the period 9th to 13th Century. They gave great patronage to the Bhakti movement saints including Nayanars. Thus, they did by making grants of land and constructing temples of Shiva and Vishnu for the saints of Bhakti movement.
2. The most beautiful temples of Shiva of South India, namely, at Chidambaram, Tanjavur and Gangaikondacholpuram were constructed under the patronage of Chola rulers.
3. During the same period some of the most spectacular representation of Shiva in bronze sculpture were produced. All this was possible because the rulers patronised the Nayanars.
4. Nayanars had considerable following among farmers.
The rulers tried to establish connections with the Nayanars and this is explained by the aforesaid description. The reason why they did is not far to seek. One reason could be to bring sanctity to the their rule. By giving alms to the temple and the preachers of Nayanar sect the rulers also announced their wealth and might. Next such acts might have endeared the rulers to the masses.
Sufi Tradition and the rulers of Delhi Sultnate and Mughals:
In the 12th Century, Delhi and a considerable part of India fell to the rule of Muslim rulers. This rule is known as the period of Delhi Sultanate. The rulers of Delhi Sultanate claimed themselves under Khalifate of Kabul and tried to legitimize their rule. The next step could have been establishing the rule of Shari‘a laws. However, the rulers realised for the very beginning that it was impractical. Under the Delhi Sultanate most of the people were not Muslim. Shari’a laws were not feasible also because lacked flexibity which a ruler needed to govern. The rulers of Delhi Sultanate wanted to take a practical path of governance without renouncing Islam. Sufi tradition gave them this opportunity. The same idea prevailed during the rule of the great Mughals too. Hence the rulers of Delhi Sultanate and the Mughal empire adopted the tradition of sufism.

8. Analyses, illustrations, why bhakti and sufi thinkers adopted a variety of languages in which to express their opinions.
Ans: In medieval India, though Sanskrit and Persian may be the language of the educated people or at the court, the vast number of people living in villages conversed in the local languages. It was, therefore, needed that the Bhakti and Sufi saints preached in the languages of the common people. This was in fact essential in order to make these movement truly popular.
This is manifested in the following examples:
1. The traditional Bhakti saints composed the hymns in Sanskrit. Such hymns were sung on special occasions often within temples.
2. The Nayanars and the Alvars were wandering saints. They travelled far and
wide, often walking on foot. They met people in different villages. These saints would sing the verses in praise of God all in the language of the local people only. The language was Tamil only. These travelling saints established temples where prayers took place in Tamil and the devotional songs were composed by the Bhakti Saints.
3. In North India the language was different. Here too the saints took to the language of the common people. Guru Nanak created Shabad all in Punjabi. Baba Farid and Swami Raidas (Ravidas) all composed in Punjabi and Hindustani.
4. Kabirdas who lived in Benaras, wrote in local language which was closer to Hindustani. He used words there part of local dialect.
5. The Sufi tradition of singing on tombs carried on in the language of the local people only. The shrines were the place of Sama sung in Hindustani or Hindavi. Another Sufi Saint Baba Farid composed in Punjabi too that even became part of Guru Granth Sahib.
6. Some other saints wrote in Kannada, Tamil and other languages too.
Thus, we are inclined to agree with the view that the Saints of Bhakti and Sufi Movement composed in many languages and the languages of the common people to connect with them.

9. Read any five of the sources included in this chapter and discuss the social and religious ideas that are expressed in them.
Ans: The social and religious ideas that are expressed in five of the sources are given below :

  1. Source 1. The Chaturvedin Brahmana versed in the four Vedas) and the “outcastes”- In this source Tondaradippodi has opposed the caste system by stating that the “outcastes” who express their love for Vishnu are better than the ‘Chaturvedins” who are strangers and without allegiance towards Vishnu.
  2. Sources 4. Rituals and the real world – In this source Basavanna who led the Virashaiva tradition in Karnataka opposed the Brahmanical rituals. In his vachana, he describes that the followers of Brahmanical traditions on seeing a serpent carved in stone, they pour milk on it but when they see a real serpent, they try to kill him. It implies that the rituals are useless.
  3. Sources 5. A church in Khambat – It is about a farman (imperial order) issued by Akbar in 1598 to the people of Khambat that no one should stand in the way of construction of a church there but should allow the padris (fathers) to build a church. This proves that Akbar followed a policy of religious toleration and people were allowed to follow any religion in his empire.
  4. Source 6. Reverence for the Jogi – It is an excerpt from a letter by Aurangzeb to a Jogi in 1661-62 sending him a piece of cloth and twenty-five rupees. It shows that till 1661-62, Aurangzeb was following a policy of religious toleration and granted help to non-Muslims. It was only later on 1678 that Aurangzeb imposed Jaziya on non-Muslims.
  5. Source 7. The pilgrimage of the Mughal princess Jahanara, 1643 – It is about Jahanara’s pilgrimage to the dargah of Shaikh Muinuddin Chishti in which she has narrated her experience. This shows that the sufi saints were revered by the royal family too. The Emperor and the members of the royal family used to visit their tombs or dargah to seek their blessings.

10. On an outline map of India, plot three major sufi shrines and three places associated with temples (one each of a form of Vishnu, Shiva and the goddess.)

11. Choose any two of the religious teachers/thinkers/saints mentioned in this chapter, and find out more about their lives and teachings. Prepare a report about the area and the times in which they lived, their major ideas, how do we know about them, and why you think they are important?
Ans: Following are the two saints of the Bhakti movement who are described as follows:
Guru Nanak:
Guru Nanak, the founder of Sikhism and the first of the ten Gurus of the Sikhs, was born in the village of Talwandi on 15th April, 1469. The village now is known as Nankana Sahib. He belonged to a Khatri caste. Before Guru Nanak departed for his heavenly abode on 22nd Sept., 1539, his name had travelled not only throughout India’s north, south, east and west, but also far beyond into Arabia, Mesopotamia (Iraq), Ceylon (Sri Lanka), Afghanistan, Turkey, Burma and Tibet.
His teachings included:
Equality of humans: Guru Nanak preached against discrimination and prejudices due to race, caste, status, etc. He said: “See the brotherhood of all mankind as the highest order of Yogis; conquer your own mind, and conquer the world.”
Universal message for all people: Normally preachers confined their preachings to the men of their own religion. But Nanak reached out. He spoke to hindus and muslims both and said to all “To take what rightfully belongs to another is like a muslim eating pork, or a hindu eating beef.”
Equality of women: Nanak promoted women’s rights and equality—a first for the 15th century! He asked:
“From woman, man is born; within woman, man is conceived; to woman he is engaged and married. Woman becomes his friend; through woman, the future generations come. When his woman dies, he seeks another woman; to woman he is bound. So should why we call her bad?
Namdeo
Saint Namdeo was born in the year 1270 in the village of Narasi-Bamani, now located in the Hingoli District in Maharashtra. He is a great Saint Poet of Maharashtra. He was one of the earliest writers who wrote in the Marathi language. He is the foremost proponent of the Bhagwad-Dharma who reached beyond Maharashtra, right into Punjab. He also wrote some hymns in Hindi and Punjabi, Namdev travelled through many parts of India, reciting his religious poems. In difficult times, he played the difficult role of uniting the pendle of Maharashtra spiritually, He is said to have lived for more than twenty years in the village of Ghuman in the Gurdaspur district of Punjab. The Sikh brethren in Punjab consider him one.

NCERT Solutions For Class 12 Biology Biotechnology Principles And Processes Q2

3. From what you have learnt, can you tell whether enzymes are bigger or DNA is bigger in molecular size? How did you know?
Ans: Both DNA (deoxyribonucleic acid) and enzymes are macromolecules. DNA is a polymer of deoxyribonucleotides and enzymes are proteins hence these are polymers of amino acids. But DNA is bigger in molecular size as compared to proteins because synthesis of proteins is regulated by a small segment of DNA, called genes and also a large number of proteins can be synthesised by a DNA molecule.

4. What would be the molar concentration of human DNA in a human cell? Consult your teacher.
Ans: The molar concentration of DNA in human cell is 2 mg/ml of cell extract.

5. Do eukaryotic cells have restriction endonucleases? Justify your answer.
Ans: No, eukaryotic cells do not have restriction endonuclease because DNA molecules of eukaryotes are heavily methylated. All the restriction endonucleases have been isolated from various strain of bacteria.

6. Besides better aeration and mixing properties, what other advantages do stirred tank bioreactors have over shake flasks?
Ans: Shake flasks are used for growing and mixing the desired materials on a small scale in the laboratory. A large scale production of desired biotechnological product is done by using ‘bioreactors’. Besides better aeration and mixing properties, the bioreactors have following advantages
(i) Small volumes of cultures are periodically withdrawn from die reactor for sampling.
(ii) It has a foam control system, pH control system and temperature control system.
(iii) Facilitates even mixing and oxygen availability throughout the bioreactor.

7. Collect 5 examples of palindromic DNA sequences by consulting your teacher. Better try to create a palindromic sequence by following base-pair rules.
Ans: Palindrome nucleotide sequences in the DNA molecule are groups of bases that form the same sequence when read both forward and backward. Five examples of palindromic DNA sequences are as follows:
(i) 5′-—————GGATCC——————3’
3′—————CCTAGG—————–5′
(ii) 5’—————AAGCTT——————3′
3′——————TTCGAA —————-5′
(iii) 5′—————–ACGCGT—————–3′
3′——————TGCGGA————– 5′
(iv) 5′———- ACTAGT————3′
3′——————TGATCA————5′
(v) 5′—————AGGCCT—————3′
3′——————TCCGGA————–5′

8. Can you recall meiosis and indicate at what stage a recombinant DNA is made?
Ans: Recombinant DNA is formed due to crossing over between non-sister chromatids of homologous chromosome. It occurs during pachytene stage of prophase of meiosis I

9. Can you think and answer how a reporter enzyme can be used to monitor transformation of host cells by foreign DNA in addition to a selectable marker?
Ans: A reporter enzyme can be used to differentiate transformed cells by tracking down the activity of its co-responding genes (receptor gene). For e.g., (3-galactosidase (Lac Z) activity is not found in transformed cells so that they appear white in colour. The others, which appear blue in colour, indicate that cells do not carry foreign DNA.

10. Describe briefly the followings:
(a) Origin of replication
(b) Bioreactors
(c) Downstream processing
Ans: (a) Origin of Replication: This is a sequence from where replication starts and any piece of DNA when linked to this sequence can be made to replicate within the host cells. This sequence is also responsible for controlling the copy number of the linked DNA. So, if one wants to recover many copies of the target DNA it should be cloned in a vector whose origin support high copy number.

(b) Bioreactor: Bioreactors can be thought of as vessels in which raw materials are biologically converted into specific products by microbes, plant and animal cell and/or their enzymes. The bioreactor provides optimum growth conditions and facilitates achieving the desired products. The most commonly used bioreactor is of stirring type. A stirred tank bioreactor is usually a cylindrical vessel or vessel with a curved base to facilitate mixing of the contents. In the sparged stirred tank bioreactor, sterile air bubbles are sparged. The stirrer facilitates the mixing and oxygen availability throughout the bioreactor. A bioreactor has an agitator system, an oxygen delivery system, a foam control system, a temperature control system, pH control system and sampling ports.

(c) Downstream Processing : The product obtained is subjected to a series, of processes collectively called downstream processing before it is made into a finished product ready for marketing. The two main processes are separation and purification. The product is then formulated with suitable preservatives. Such formulations have to undergo clinical trials, in case of drugs.

11. Explain briefly
(a) PCR
(b) Restriction enzymes and DNA
(c) Chitinase
Ans: (a) PCR = Polymerase chain reaction (in vitro method) is a molecular biological technique for enzymatically replicating DNA without using a living organism, such as E. coli or yeast.
3 steps in PCR are –
(i) Denaturation of desired double strand DNA-to ssDNA.
(ii) Annealing of primer to ssDNA (single standard).
(iii) Extension of primer by Taq DNA polymerase isolated form Thermits aquaticus.
Uses – Amplification of desired gene/gene cloning.
Advantage- More output, greater efficiency, less error prone, less human interference and cyclic and automated.
(b) Restriction enzymes and DNA – Restriction enzymes is a group of enzymes used to cleave or cut DNA strands each having a characteristics base sequence at which it cleaves.
(i) It restricts foreign DNA from entering normal cell by digesting it at various recognition site. Recognition site is palindromic.
(ii) They are endonuclease and exonuclease both types.
(iii) They produces sticky ends. Cleavage site and recognition site are different from each other. Restriction enzymes therefore are believed to be a mechanism evolved by bacteria to resist viral attack and to help in the removal of viral sequences.
(c) Chitinase – Chitinase is a enzyme to digest or breakdown glycosidic bonds in chitin cell wall of fungal cell to facilitate its transformation.

NCERT TEXTBOOK QUESTIONS SOLVED

1. Describe the process of manuscript production in the Mughal court.
Ans: Process of manuscript production in the Mughal court included the following:
(a) Paper-maker’s responsibility was to prepare the folios of the manuscript.
(b) Skill writer, i.e. scribes or calligrapher copied the texts.
(c) Guilders, illuminated the pages of the manuscript.
(d) Miniature painter illustrated the scene from the text.
(e) The book binders gathered the folio and gave it to the original shape of a book.

2. In what ways would the daily routine and special festivities associated with the Mughal court have conveyed a sense of the power of the emperor?
Ans: The daily routine and special festivities associated with the Mughal court would have conveyed a sense of the power of the emperor in the following ways :

  1. The emperor, after personal religious prayers, appeared on a small balcony for Jharoka darshan, before a crowd of people for darshan of the emperor. The Jharoka darshan was introduced by Akbar with the objective of broadening the acceptance of the imperial authority as part of the popular faith.
  2. The focus of the physical arrangement of the court was on the sovereign. It mirrored his status as the heart of society. Its centrepiece was, therefore, the throne, the takht which gave physical form to the function of the sovereign as pillar.
  3. The rules regarding status of the Mughal elites were laid down with great precision. In court, status was determined by spatial proximity to the emperor.
  4. Once the emperor sat on the throne, no one was permitted to move from his position or to leave without permission.
  5. Whenever the court or darbar was held, all who had admittance were required to make the kornish.
  6. The forms of salutation to the ruler indicated the person’s status in the hierarchy. Deeper prostration represented higher status.
  7. The diplomatic envoys like ambassador were expected to offer an acceptable form of greeting — either by bowing deeply or kissing the ground or else to follow the Persian custom of clasping one’s hands in front of the chest.
  8. Special occasions such as Id, Shab-i barat anniversary of accession to the throne, festivals — the solar and lunar birthdays of the monarch were celebrated in such a way that left tremendous impression on visitors.
  9. Grand titles were adopted by the Mughal emperors at the time of coronation or after a victory over an enemy.
  10. Mughal coins carried the full title of the reigning emperor with regal protocal.
  11. A courtier always approached the emperor with gifts. He generally offered a small sum of money (nazr) or a large amount (peshkash).
  12. Even in diplomatic relations, gifts were regarded as a sign of honour and respect.

3. Assess the role played by women of the imperial household in the Mughal Empire
Ans: (i) The term “haram” is used to describe the domestic world of the Mughals. This word is taken from the Persian word haram, which means a sacred place.
(ii) The Mughal household consisted of the emperor’s wives and concubines, his near and distant relatives (mother, step- and foster-mothers, sisters, daughters, daughters-in-law, aunts, children, etc.), and female servants and slaves.
(iii) Polygamy was practised widely in the Indian subcontinent, especially among the ruling groups. Both for the Rajput clans as well as the Mughals marriage was a way of cementing political relationships and forging alliances.
(iv) The gift of territory was often accompanied by the gift of a daughter in marriage. This ensured a continuing hierarchical relationship between ruling groups. It was through the link of marriage and the relationships that developed as a result that the Mughals were able to form a vast kinship network that linked them to important groups and helped to hold a vast empire together.
(v) In the Mughal household a distinction was maintained between wives who came from royal families (begams), and other wives (aghas) who were not of noble birth.
(vi) The begams, married after receiving huge amounts of cash and valuables as dowry (maahr), naturally received a higher status and greater attention from their husbands than did aghas. The concubines (aghacha or the lesser agha) occupied the lowest position in the hierarchy of females intimately related to royalty.
(vii) The agha and the aghacha could rise to the position of a begam depending on the husband’s will, and provided that he did not already have four wives.
(viii) Love and motherhood played important roles in elevating such women to the status of legally wedded wives. Apart from wives, numerous male and female slaves populated the Mughal Household. The tasks they performed varied from the most mundane to those requiring skill, tact and intelligence.
(xi)Slave eunuchs (khwajasara) moved between the external and internal life of the household as guards, servants, and also as agents for women dabbling in commerce.

4. What were the concerns that shaped Mughal policies and attitudes towards regions outside the subcontinent?
Ans: (i) The Safavids and Qandahar: The political and diplomatic relations between , the Mughal kings and the neighbouring countries of Iran and Turan hinged on the control of the frontier defined by the Hindukush mountains that separated Afghanistan from the regions of Iran and Central Asia. A constant aim of Mughal policy was to ward off this potential danger by controlling strategic outposts – notably Kabul and Qandahar. The fortress-town Qandahar had initially been in the possession of Humayun, reconquered in 1595 by Akbar.The Safavid court retained diplomatic relations with the Mughals, it continued to stake.claims to Qandahar. Jahangir sent a diplomatic envoy to the court of Shah Abbas in 1613 to plead the Mughal case for retaining Qandahar, but the mission failed to achieve its objectives. Persian army besieged Qandahar in 1622. The Mughal garrison was defeated and had to surrender the fortress and the city to the Safavids.

(ii) The Ottomans: pilgrimage and trade: The relationship between the Mughals and the Ottomans ensured free movement for merchants and pilgrims in the territories under Ottoman control. This was especially true for the Hijaz, that part of Ottoman Arabia where the important pilgrim centres of Mecca and Medina were located.
The Mughal emperor combined religion and commerce by exporting essential goods to Aden and Mokha, and distributing the proceeds of the sales in charity to the keepers of shrines and religious men there.

(iii) Jesuits at the Mughal court: European received knowledge about India through the accounts of Jesuit missionaries, travellers, merchants and diplomats. After the discovery of sea route to India, the Portuguese merchants set up their trading network stations in coastal region. The Portuguese was also interested in the spread of Christianity with the help of the missionaries of the Society of Jesuits. The Christian missions who sent to India during the sixteenth century were part of this process of trade and empire building. The first Jesuit mission reached the Mughal court of Mughal emperor Akbar at Fatehpur oikri in 1580 and stayed here for about two years. The Jesuits spoke to Akbar about Christianity and debated its virtues with the ulema. Two more missions were sent to the Mughal court at Lahore, in 1591 and 1595. The Jesuit accounts are based on personal observation and shed light on the character and mind of the emperor. At public assemblies the Jesuits were assigned places in close proximity to Akbar’s throne.. The Jesuit accounts corroborate the information given in Persian chronicles about state officials and the general conditions of life in Mughal times.

5. Discuss the major features of Mughal provincial administration. How did the centre control the provinces ?
Ans:

  1. The Mughal provincial administration was like the central administration as mentioned below :
    • There were diwan, bakhshi and sadr corresponding the central ministers – Diwan-i ala, mir-bakshi and sadr-us sudur.
    • The head of the provincial administration was the governor (subadar) who directly reported to the emperor.
    • A suba was divided into sarkars.
    • Faujdars were deployed with contingents of heavy cavalry and musketeers in districts.
    • At the local level were parganas which were looked after by the qanungo (keeper of revenue records), the chaudhuri (in charge of revenue collection) and the qazi.
    • There was clerks, accountants, auditors, messengers and other functionaries who were technically qualified officials. They functioned with standardised rules and procedures.
    • Persian was the language of the administration but local languages were used for village accounts.
  2. The Mughal emperor and his court controlled the entire administrative apparatus down to the village level. However, the relationship between local landed magnates, the zamindars, and the representatives of the Mughal emperor was sometimes marked by conflicts over authority and a share of the resources. Moreover, after the death of Aurangzeb the provincial governors became powerful and this led to the downfall of the Mughal Empire.

6. Discuss, with examples, the distinctive features of Mughal chronicles.
Ans: (i) Chronicles commissioned by the Mughal emperors are an important source for studying the empire and its court. They were written in order to project a vision of an enlightened kingdom to all those who came under its umbrella. The authors of
Mughal chronicles focused on events-related to life of the ruler, their family, the court and nobles, wars and administrative
system.

(ii) These chronicles were written in Persian. This language flourished as a language of the court and of literary writings, alongside north Indian languages, especially Hindavi and its regional variants. As the Mughals were Chaghtai Turks by origin, Turkish was their mother tongue.

(iii) Chronicles narrating the events of a Mughal emperor’s reign contained, alongside the written text, images that described an event in visual form.

(iv) When scenes or themes in a book were to be given visual expression, the scribe left blank spaces on nearby pages; paintings, executed separately by artists, were inserted to accompany what was; described in words.

Question 7.
To what extent do you think the visual material presented in this chapter corresponds with Abu’l Fazl’s description of the taswir (Source 1)?
Solution :
Abu’l Fazl held the art of painting in high esteem. Drawing the likeness of anything was called taswir. Many paintings were masterpieces which could be compared with wonderful works of the European painters. The minuteness in detail, the general finish and the boldnesss of execution observed in pictures were incomparable. Such was the observation of Abu’l Fazl about the taswir. The visual material presented in this corresponds to the above description to a great extent in the followings ways :

  1. In the picture, ‘A Mughal Kitabkhana’, every work relating to the preparation of the manuscript has been shown minutely.
  2. In another painting by Abu’l Hasan, Jahangir has been shown dressed in resplendent clothes and jewels, holding up a portrait of his father Akbar. The emperors have been portrayed wearing halo.
  3. In another painting by the artist Prayag, Jahangir is presenting Prince Khurram with a turban jewel. It is a scene from the Badshah Nama. The artist has also used the motif of the lion and the cow peacefully nestling next to each other to signify a realm where both the strong and the weak could exist in harmony. It has been placed in a niche directly below the emperor’s throne.

The above and other paintings — Jahangir shooting the figure of poverty (Abu’l Hasan), Shah Jahan honouring Prince Aurangzeb at Agra before his wedding (Payag), Dara Shukoh’s wedding — meet the above description of Abu’l Fazl.

8. What were the distinctive features of the Mughal nobility? How was their relationship
with the emperor shaped?
Ans: Recruitment, rank of the n ability and relationship with the emperor:
(i) Mughal chronicles, especially the Akbar Nama, have bequeathed a vision of empire in which agency rests almost solely with the emperor, while the rest of the kingdom has been portrayed as following his orders, if we look more closely at the available information the histories provide us about the apparatus of the Mughal state, we may be able to understand the ways in which the imperial organisation was dependent on several different institutions.

(ii) The most important pillar of the Mughal state was the nobility. The nobility was recruited from diverse ethnic and religious group which ensured that no faction was large enough to challenge the authority of the state.

(iii) The officer corps of the Mughals was described as a bouquet of flowers (guldasta) held together by loyalty to the emperor. In Akbar’s imperial service, Turani and Iranian nobles were present from the earliest phase of carving out a political dominion. Many had accompanied Humayun; others migrated later to the Mughal court.

(iv) The holders of government offices was given the ranks (mansabs) comprising two numerical designations: zat which was an indicator of position in the imperial hierarchy and the salary of the official (mansabdar), and sawar which indicated the number of horsemen he was required to maintain in service.

(v) Akbar, who designed the mansab system, also established spiritual relationships with a select band of his nobility by treating them as his disciples (murid).

(vi) For members of the nobility, imperial service was a way of acquiring power, wealth and the highest possible reputation. A person wishing to join the service petitioned through a noble, who presented a tajwiz to the emperor.

(vii) If the applicant was found suitable, a mansab was granted to him. The mir bakhshi (paymaster general) stood in open court on the right of the emperor and presented all candidates for appointment or promotion, while his office prepared orders bearing his seal and signature as well as those of the emperor. There were two other important ministers at the centre: the diwan-i ai (finance minister) and sadr-us sudur (minister of grants or madad-i maash, and in charge of appointing local judges or qazis)

(viii) The three ministers occasionally came together as an advisory body, but were independent of each other.

(xi) Akbar with these and other advisers shaped the administrative, fiscal and monetary institutions of the empire. Nobles stationed at the court (tainat-i rakab) were a reserve force to be deputed to a province or military campaign. Nobles were duty-bound to appear twice a day to express submission their to the emperor.
(x) They also had to share the responsibility for guarding the emperor and his household round the clock.

9. Identify the elements that went into the making of the Mughal ideal of kingship.
Ans: (i) According to Akbars court poet, Abu’l Fazl Mughal kingship as the highest station in the hierarchy of objects receiving light emanating from God (farr-i- izadi). According to this idea, there was a Hierarchy in which the Divine Light was transmitted to the king (Mughal Emperor) who then became the source of spiritual guidance for his subjects.

(ii) Mughal chronicles present the empire as comprising many different ethnic and religious communities – Hindus, Jainas, Zoroastrians and Muslims. As the source of all peace and stability, the emperor stood above all religious and ethnic groups, mediated among them, and ensured that justice and peace prevailed.

(iii) Abu’l Fazl describes the ideal of sulh-i kui (absolute peace) as the cornerstone of enlightened rule. In sulh-i kul all religions and schools of thought had freedom of expression but on condition that they did not undermine the authority of the state or fight among themselves The ideal of sulh-i kul was implemented through state policies – the nobility under the Mughals was a composite one comprising Iranis, Turanis, Afghans, Rajputs, Qeccanis – all of whom were given positions and awards purely on the basis of their service and loyalty to the king.

(iv) Akbar abolished the tax on pilgrimage in 1563 and jizya in 1564 as the two were based on religious discrimination. Instructions were sent to officers of the empire to follow the concept of sulh-i kul.

(v) All Mughal emperors gave grants to support the buildings and maintenance of places of worship. However, it was during the reign of Auranzeb, the jizya was re¬imposed on non-Muslim subjects.

(vi) Abu’l Fazl defined sovereignty as a social contract. According to him the emperor protects the four essences of subjects, namely, life (jan), property (mal), honour (narnus) and faith (din), and in return demands obedience and a share of resources from the people. Only sovereigns were thought to be able to honour the contract with power and Divine guidance.

NCERT TEXTBOOK QUESTIONS SOLVED

1. Write a note on the Kitab-ul-Hind.
Ans: Kitab-ul-Hind was written by Al-Biruni in 1031. It was considered with India and also known by the name of Tarikh-ul-Hind and Tahqiq-ma-ul-Hind. It was written in Arabic. It is divided into 80 Chapters. They have thrown a detailed light on Hindu religions and philosphy, festivals, customs and tradition, the social and economic as well as political life of the people. In each chapter he adopted a distinctive style and had a question in the beginning. It was followed by a description based on Sanskrit tradition, At last he compare the India culture with other culture. This geometric structure he followed is known for its precision and predictability. The main reason for this structure was Al-Biruni’s mathematical orientation.

2. Compare and contrast the perspectives from which Ibn Battuta and Bernier wrote their accounts of their travels in India.
Ans: Ibn Battuta was an early globe-trotter. He considered experience gained through travels to be a more important source of knowledge than books. He meticulously recorded his observations about new cultures, peoples, beliefs and values. He enjoyed the cosmopolitan culture of urban centres where people who spoke Arabic, Persian, Turkish and other languages, shared ideas, information and anecdotes. He highlighted unfamiliar things in order to ensure that the listener or the reader was suitably impressed by accounts of distant yet accessible worlds. For example, he described the coconut and the paan which was completely unfamiliar to his readers. Thus, Ibn Battuta described everything that impressed and excited him because of its novelty.

Francois Bernier, on the other hand, belonged to a different intellectual tradition. He tried to compare and contrast what he saw in India with the situation in Europe in general and France in particular, focusing on situations which he considered depressing. His idea was to influence the policy makers and intelligentsia to ensure that they made what he considered to be the “right” decisions. He compared Mughal India with contemporary Europe. He emphasised the superiority of Europe. His representation of India works on the model of binary opposition, where India is presented as the inverse of Europe. He also ordered the perceived differences hierarchically, so that India appeared to be inferior to the Western world.

3. Discuss the picture of urban centres that emerges from Bernier’s accout.
Ans: During the 17th century nearly 15% of population was living in town. This was average proportion of urban population of western Europe. Bernier described Mughal towns as court towns. By it he meant those towns which depended upon the imperial court for their existence and survival. These towns came into existence with the imperial court and declined with the impanel court when they moved to other places. In his travel accounts, Bernier described many big towns and cities such as Delhi, Mathura, Kashmir, Surat, Masulipatnam and Golconda. These gained importance as manufacturing centres, trading towns, and sacred towns. The merchant communities had deep influence in these cities. They remained organised due to their own caste and occupational bodies. These trading groups were known as Mahajans in western India. Their head was called Sheth. In Ahmedabad, the chief of Merchant community was known as nagarsheth. Besides the trading groups, musicians, architects, painters, lawyers, calligraphies, etc. lived in towns.

4. Analyse the evidence for slavery provided by Ibn Battuta.
Ans: Battuta has given a detailed description on the practice of slavery prevalent in India. Delhi Sultan-Muhammad bin Tughlaq had a large number of slaves. Most of these slaves were forcibly captured during the aggressions. Many people sold their children as a slave, because of acute poverty. Slaves were also offered as a gift during this time. Battuta when visited him, also brought many horses, camels and slaves for the Sultan to present him. Sultan Muhammad bin Tuglaq, himself had presented two hundred slaves to Nasiruddin a religious preacher.

Nobels are used to keep slave those days. Through these slaves, the Sultan used to get information about the activities of the noble and all other important events of the empire.

The woman slaves served as servants in the house of the rich (nobles). These women informed the Sultan about the activities of their masters (i.e., nobles). Most of the slaves used to do domestic works and there was a lot of difference between the status of these slaves and the court slaves.

5. What were the elements of the practice of sati that drew the attention of Bernier?
Ans: The practice of sati according to Bernier showed the difference in the treatment of women in western and eastern society. He noticed how a child widow were forcefully burnt screaming on the funeral pyre while many of the older women were resigned their fate.
The following elements drew his attention.
(i) Under this cruel practices an alive widow was forcibly made to sit on the pyre of her husband.
(ii) People had no sympathy for her.
(iii) The widow was an unwilling victim of the sati-practice. She was forced to be a Sati.

6. Discuss Al-Biruni’s understanding of the caste system.
Ans: Al-Biruni’s description about caste system as he understood. Al-Biruni tried to explain the caste system by looking far parallels in other societies. He described that in ancient Persia, four social categories were recognised.
(i) knight and princes.
(ii) monks
(iii) fire-priests and lawyers; physicians, astronomers, other scientists;
(iv) Finally, peasants and artisans. He attempted to suggest that social divisions were not unique to India.

His description of the caste system in India was deeply influenced by his study of Sanskrit texts. According to these texts, the highest castes were the Brahmins as they were created from the head of the Brahmins.

The Kshatriyas were the next caste created from the shoulders and hands of the Brahmin. The Vaishyas and Shudras were created from the thighs and feet of the Brahmin respectively.

Thus, he sought to understand the Indian caste system by looking for parallels in other societies. Nothing that ancient Persian society was divided into four categories he realized that social division was not unique to India.

But despite accepting the caste system he was against the notion of pollution. He believed that according to the laws of nature anything which becomes impure ultimately becomes pure again, e.g. the sun clears the air. The concept of social pollution is the bedrock of the caste system. Thus, the caste system was according to him contrary to the laws of nature.

He failed to realize that the caste system was not as rigid as portrayed in the Sanskrit texts.

7. Do you think Ibn Battuta’s account is useful in arriving at an understanding of life in contemporary urban centres ? Give reasons for your answer.
Ans: Ibn Battuta found cities full of opportunities for those who had the necessary drive, resources and skills. They were densely populated and prosperous, except for the occasional disruptions caused by wars and invasions. According to Ibn Battuta, it appears that most cities had crowded streets and bright and colourful markets. He described Delhi as a vast city, with a great population, the largest in India. In his description of Delhi, he stated, “The rampart around the city is without parallel. … It has many towers …. There are twenty eight gates of this city which are called darwaza.” The bazaars were centres of economic, social and cultural activities.

  1. The Ibn Battuta’s account is useful in arriving at an understanding of life in contemporary urban centres because the description seems to be correct. For example, the older cities in India have crowded streets and bazaars full of variety of goods. Delhi was and still is a vast city. The older portion of Delhi has crowded streets and its bazaars are full of all types of goods.
  2. In addition to above it may be stated that when Ibn Battuta arrived in Delhi in the fourteenth century, the subcontinent was part of a global network of communication that stretched from China in the east to north-west Africa and Europe in the west.
  3. The Indian agriculture was also productive due to fertility of the soil. This led to prosperity of towns because the towns derived a significant portion of their wealth through the appropriation of surplus from villages.
  4. The Indian goods were in great demand in both West Asia and Southeast Asia which fetched huge profits for artisans, merchants and Indian textiles.

8. Discuss the extent to which Bernier’s accounts enables historians to reconstruct contemporary rural society.
Ans: Bernier’s assessment about Indian rural society was not correct. It was far away from the truth, but it is not acceptable. There are some truth in his description which are evident from the following facts.
(i) According to his account, mughal empire was the owner of the land and distributed among its nobles. It had a disastrous impact on the society.
(ii) According to him the system of crown of ownership of land was good. It was because, the land holders could not pass on their land to their children. They did not make any long term investment on the land.
(iii) As there was no private property in land, there was not any improvement in the landlord class. This system ruin agriculture and led to opinion of peasants. Bernier’s view regarding Indian society had the following features:
(i) The rich people Were in minority.
(ii) It had the poorest of the poor and the richest of the rich, no middle class existed there.
(iii) All the cities and towns were reined and had contaminated air.

QUESTIONS FROM TEXTBOOK SOLVED

1. Name the three important components of  biodiversity.
Ans: Three components of biodiversity are:
(a) Genetic diversity
(b) Species diversity
(c) Ecological diversity

2. How do ecologists estimate the total number of species present in the world?
Ans: Ecologists estimate the total number of species present in the world by comparing species richness of some exhaustively studied groups between any two regions (tropics, temperate or polar regions). Species richness, as a measure of diversity, has been used by many ecologists. Species density or the number of species per m² is most commonly used to measure species richness. Species abundance and species proportional abundance based indices are some other alternative approaches to the measurement of diversity.

3. Give three hypothesis for explaining why tropics ’”show greatest levels of species richness.
Ans: (1) The tropical area have a more stable climate than temperate zones. Local species continues to live in absence of natural disturbances.
(2) Warm temperature and high humidity in most tropical areas provide favourable conditions for growth and survival of diverse species.
(3) Tropical areas receive more solar energy over year and thus tropical communities are more productive and can support a wide range of species.

4. What is the significance of the slope of regression in a species-area relationship?
Ans: Slope of regression or regression coefficient makes it easier to measure species richness along an area. For a limited area like, a country, it gives a constant value of 0.1 to 0.2 irrespective of the taxonomic group or region. It remains amazingly similar for all those small regions. On the contrary, for measuring species-area relationship over large areas like the entire continents, the slope of regression values in the range of 0.6 to 1.2.

5. What are the major causes of species losses in a geographical region?
Ans: Species are lost in a geographical region due to natural disturbances like forest fires; famine, drought and also due to human disturbance with over replantation, habitat destruction, habitat displacement, over specialization, intensive agriculture and pollution.

6. How is biodiversity important for ecosystem functioning?
Ans: Biodiversity is important for ecosystem functioning because,
(1) It contributes to productivity.
(2) It cause more efficient recycling of energy and matter.
(3) It has many alternative pathways for survival under diverse conditions.
(4) Rich biodiversity provides alternatives available at each trophic level. All organisms are linked in food chains and interact with their abiotic environment in such a way so as to keep the natural cycles going and make the ecosystems self – sustaining units. Disappearance of any link in a food chain will not affect the ecosystem as other alternatives are there.

7. What are sacred groves? What is their role in conservation?
Ans: Sacred forests or sacred groves are forest patches around places of worship which are held in high esteem by tribal communities. They are the most undisturbed forest patches which are often surrounded by highly degraded landscapes. They are found in several parts of India, e.g., Karnataka, Maharashtra, Rajasthan (Aravalli), Madhya Pradesh (Sarguja, Bastar), Kerala, Meghalaya. Temples built by tribals are found surrounded by deodar forests in Kumaon region, Jaintias and Khasjas in Meghalaya. Not a single branch is allowed to be cut from these forests. As a result many endemic species which are rare or have become extinct elsewhere can be seen to flourish here. Bishnois of Rajasthan protect Prosopis cineraria and Black Buck religiously. Some water bodies are also held sacred in certain places, e.g., Khecheopalri in Sikkim. Their aquatic flora and fauna are naturally preserved.

8. Among the ecosystem services are control of floods and soil erosion. How is this achieved by the biotic components of the ecosystem?
Ans: Ecosystem services are products or benefits given by ecosystem processes to the environment for its purification, beauty, biodiversity, protection of natural resources, habitat to wild life and tribals, protection of soils, CO2 – O2 balance, retention of water against floods, drought and pollution. Plants play a vital role in the control of floods and soil erosion. Their roots bind the soil 10. particles firmly and in this way they do not allow the top soil to be drifted away by winds or moving water. Roots of plants also make the soil porous and allow water to go into the soil.

9. The species diversity of plants (22 per cent) is much less than that of animals (72 per cent). What could be the explanations to how animals achieved greater diversification?
Ans: Species diversity refers to the variety of species within a region which is less in plants as compared to animals. It is due to greater dispersal/more number of surviving individuals. Most animals possess simple or complex nervous system to control and coordinate various activities. They possess receptors to receive against them. Most of their responses are adaptive and ensure their survival in changing environmental conditions. They, therefore, have evolved to reveal much higher species diversity than plants who do not possess nervous system and respond differently against environment stimuli.

10. Can you think of a situation where we deliberately want to make a species extinct? How would you justify it?
Ans: Humans can cause extinction of species through various means. We are trying to eradicate disease causing organisms (e.g., poliovirus) from this world to make this world disease free. Since such micro-organisms are harmful to the human society, such attempt is justified. Further, such micro-organisms are not essential components (producers or decomposers) of any ecosystem, and losing one or few such organisms would not affect the functioning of ecosystem.
