Chapter 1 Control and Co-ordination in Living Organisms

Chapter 1A Sensitivity and Response in Plants:
Discussions should include the following along with relevant diagrams: Living organisms exist in changing environments. Some changes are favourable and advantageous, while others are unfavourable or harmful. Sensitivity is the ability of organisms to detect change and respond to it. Changes that are detected and lead to responses are termed stimuli. Stimulus is a kind of energy. All living organisms respond to stimuli of one kind or another. Many stimuli arise externally from an organism, but others from an organism’s internal environment. As most plants are anchored organ¬isms, plant responses are less evident than those of animals. Rapid movements by plants are extremely rare. Generally, plant responses are slow growth movements or turgor movements. Explain plant sensitivity and response citing movements in mimosa and Desmodium. Brief mention of the contribution of Acharya Jagdish Chandra Bose in discovering the sensitivity of plants. Brief mention of plant movement as a response to stimuli. Types of plant movement: Tactic, Phototactic, Tropic: Phototropic, Hydrotropic, Geotropic, Nastic: Photonastic, Thermonastic, Seismonastic, Chemonastic (Brief mention of the stimuli and response in each case and one or two examples of each with relevant diagrams.) Comparison between Tactic, Tropic, and Nastic movements in Tabular form.

Chapter 1B Response and Chemical Co-ordination in Plants – Hormones:
A brief discussion on plant hormones as substances responsible for sensitivity and response in plants. Also mention hormones as plant growth substances mentioning the phenomena of apical and lateral growth, flowering, bud break, germination of seeds, and tropic movement in plants.

Brief mention of the origin, chemical constituent (mention C, H, O, N only), and the role (as mentioned below) of Auxin, Gibberellin, and Cytokinin in plants with relevant diagrams. Auxin: Promotes apical dominance and inhibits lateral bud growth, cell division and cell enlargement, root growth at very low concentrations, fruit growth, and control of tropic movement. Gibberellin: Breks seed and bud dormancy, elongation of internodes, fruit growth. Cytokinin: Promotes cell division, and lateral bud growth, delays leaf senescence. Chemical names of synthetic hormones are not to be mentioned. The terms synthetic auxin and synthetic gibberellin can be used. Mention the role of synthetic hormones – rooting of cutting, dealy of pre-harvest fruit crop, artificial auxin as herbicide, developing parthenocarpic fruits.

Chapter 1C Response and Chemical Co-ordination in Animals – Hormones:
Briefly mention the erection of body hair, maintaining a constant level of glucose in the blood, combating stress, maintaining blood pressure, controlling BMR, control growth and secretion of reproductive glands in animals. Briefly mention the need for regulatory chemical molecules namely hormones for controlling these functions. Explain the source (endocrine glands), chemical nature, mode of transport, functioning, and fate of hormones; Explain the role of the hormone as messenger and regulator (feedback control with an example – TSH and Thyroxine). Mention the differences between plant hormones and animal hormones (in tabular form). Hypothalamus: Controls hormonal secretions of the anterior pituitary gland & produces the hormones of the posterior pituitary gland (ADH and Oxytocin). They remain stored in the posterior pituitary gland and released later on. Pituitary: ACTH, GH, TSH, GTH (FSH, LH, ICSH, LTH/Prolactin), ADH, Thyroid: Thyroxine, Adrenal: Adrenalin, Nor- adrenalin, Endocrine Pancreas: Insulin, Glucagon, Gonads: Testes – Testosterone, Ovary – Oestrogen, Progesterone. The name of endocrine glands, their location, the hormones secreted, and their role in the human body are to be mentioned. Causes and symptoms of the following hormonal disorders are to be mentioned separately – dwarfism, diabetes insipidus, goiter, and diabetes mellitus. A diagram of the human body is to be provided to show the location of the endocrine glands mentioned above. Mention the difference between endocrine and exocrine glands based on the following features (in tabular form): (i) Presence or absence of ducts, (ii) Place of action, (iii) Product secreted.

Chapter 1D Response and Physical Coordination in Animals – Nervous System:
Explaination in brief about neural control and coordination with examples from daily life, setting the stage for introducing neurons, nerves, and the nervous system. One example may be running: leg muscles need extra supplies of glucose and oxygen – Lungs breathe faster and deeper and the heart pumps rapidly to supply oxygen and glucose to the muscles quickly – the brain detects changes in oxygen and carbon dioxide content of the blood and sends nerve impulses to the diaphragm, intercostal muscles, and heart. The coordination of different systems is thus brought by the nervous system. Discussions should include the following along with relevant diagrams: Irritability or sensitivity is a characteristic feature of all living organisms. It refers to their ability to respond to a stimulus. The stimulus is received by a receptor. It is transmitted by means of nerves. Finally, an effector (muscle and gland) brings about a response. Between the receptors and effectors are the conducting cells of the nervous system, termed neurons. These are the basic structural and functional units of the nervous system. They are spread throughout the organism forming a complex communication network. Some common examples may be given to illustrate the pathway: Stimuli – Receptor – Nervecentre – Effector – Response (e.g. opening the door at the sound of a knock on the door/ doorbell). Mention the difference between the mode of action of hormones and the nervous system. Explain the structure and function of different parts of neurons (in tabular form with diagrams); Mention the neuroglia as supporting cells of the nervous system.

Brief mention of binocular vision in humans and how it differs from monocular vision.

Chapter 1E Locomotion as a Type of Response in Animals:
Discussions should include the following along with relevant diagrams (for near and distant vision). Example from one daily life situation (Role of accommodation in case of pedestrians and vehicle drivers to avoid road accidents by taking note of obstacles, traffic signals, and road directions). The curvature of the lens can be modified to some extent by the ciliary muscles. The change in curvature of the lens can thus change its focal length. Accomodation is the ability of the eye lens to adjust its focal length. The eye adjusts the shape of the lens to keep objects in focus. Looking at distant objects: Ciliary muscles relaxed – Lens becomes thin – focal length of the lens increases. Looking at objects closer to the eye: Ciliary muscles contract – increasing curvature of the eye lens – Lens becomes thick – focal length of the lens decreases. Brief mention of the loss of power accommodation and in this context mention myopia, hyperopia, presbyopia, and their corrective measures (lenses used for correction) with diagrams. Cataract Brief explanation and corrective measure.

Chapter 2 Continuity of Life

Chapter 2A Cell Division and Cell Cycle:
Discussions should include the following along with relevant diagrams of DNA double helix (ribbon diagram), chromatin reticula, and chromosomes. Inside the nucleus of a cell, Fine reticulum-like structures are woven like threads around each other structures are DNA. DNA is a large biomolecule. The DNA remains in folded or partly open condition inside the nucleus, which is then termed as Chromatin Reticulum. In the folded condition, the DNA is wound tightly around proteins. This folded structure of DNA is termed a Chromosome. Chromatin reticula and chromosomes are actually different folding states of DNA molecules. Specific parts of the DNA carry the code for producing specific proteins which ultimately lead to the expression of different characters in an organism. Each of these parts of DNA is termed a Gene. Autosome and Sex Chromosome – Brief explanation with reference to humans. Mention the number of chromosomes in body cells and gametes in humans and briefly explain haploid and diploid states with reference to humans. Briefly explain the following in tabular form with diagrams Chromatid, Primary constriction or Centromere, Secondary constriction, oatelite, Telomere.

Brief mention of the events (G,, S, G2, M) of the cell cycle with diagram and significance of the cell cycle (Mention that the loss of control at different points in the cell cycle results in uncontrolled cell division leading to formatting of tumor sometimes may becomes malignant and may result in cancer). Brief explanation with diagrams of different stages of Mitosis in plant and animal cells (Karyokinesis & its stages and Cytokinesis). Mention the difference between plant and animal mitosis based on the following features: (i) Formation of spindle fiber; (ii) Process of cytokinesis; Mention the significance of mitosis-growth, cell replacement & repair (eg. skin), regeneration (eg. legs in crustacean and arms in starfish), reproduction. Brief introduction of homologous chromosomes, sister and non-sister chromatid. A brief explanation of the following features of meiosis with the help of relevant diagrams: Separation of homologous chromosomes in Meiosis I as opposed to the separation of chromatids in Mitosis; separation of chromatids in Meiosis II (just like Mitosis); Reduction in chromosome number; Crossing over (exchange or segments between non-sister chromatids of homologous chromosomes). (The stages of meiosis are not mentioned.) The significance of meiosis is to be mentioned (maintenance of constant chromosome number of a species, producing variation in organisms, formation of gametes, alternation of generation). The basic differences between mitosis and meiosis are to be mentioned in tabular form based on the following features – (i) site of occurence; (ii) nature of division of chromosomes (equational as opposed to reductional); (iii) number of cells produced.

Chapter 2B Reproduction:
Discussions should include the following along with relevant examples: Reproduction is the production of a new generation of individuals of the same species. It is one of the fundamental characteristics of living organisms. Reproduction is not necessary to maintain the life of an individual organism, unlike essential life processes like nutrition, respiration, or exertion. But reproduction is essential for the continuation of species. A brief explanation of the modes of reproduction with one or two examples of each – Asexual and sexual. Difference between asexual and sexual reproduction based on the following features: (i) Number of parents; (ii) Production of gametes; (iii) Dependence on mitosis or meiosis; (iv) Nature of offspring.

Types of vegetative propagation (brief explanation with one example of each): Natural – Root: Fleshy root (Sweet potato); Stem; Offset (Water hyacinth); Leaf: Adventitious bud (Bryophyllum). Artificial – Cutting, Grafting, and Micropropagation. Discussion on micropropagation should include only the following: ‘Micro’ refers to the small size of the material used, usually isolated cells or small pieces of tissue. The material is grown in special culture solutions (with added nutrients and plant hormones, particularly auxins and cytokinins), so the process is also known as tissue culture. Basically, it is the propagation of plants by tissue culture. This process ensures rapid propagation of desired varieties of plants. Brief explanation with a schematic diagram of alternation of generation with one example from germ. Discussions should include the following with relevant diagrams: (i) Different parts of a flower – sepals, petals, stamens, and carpels; (ii) Stamens and carpels – the reproductive parts of a flower containing germ cells; (iii) Stamen – male reproductive part; produces pollen grains of yellowish colour; (iv) Carpel – female reproductive part; consists of stigma, style, and ovary; ovary contains ovules and each ovule has an egg cell. A brief explanation of pollination and its types (self and cross-pollination) with examples and diagrams. Merits and demerits of self and cross-pollination in tabular form are to be mentioned based on the following – (i) the necessity of agents and (ii) the emergence of new characters in the offspring. A brief explanation of agents of pollination with one common example of each in tabular form – air (paddy), water (hydrilla), insect (mango), and bird (shimul). Discussions should include the following with relevant diagrams: Pollen grains transferred from the stamen to the stigma – male germ cells produced by pollen grain fuses with female gamete present in ovule – fusion of germ cells (fertilization) – zygote – divides several times to form embryo within the ovule – ovule gradually converts into seed and the ovary grows and ripens to form a fruit – seed contains future plant or embryo which develops into a seeding under appropriate conditions (Double fertilization and development of endosperm not to be mentioned). Discussions should include the following with relevant diagrams: Growth is a fundamental characteristic of all living organisms. The growth of an organism consists of a permanent and more or less irreversible increase in size and shape, commonly accompanied by an increase in solid matter, dry mass, and amount of cytoplasm. It is basically an irreversible increase in dry mass of living material. The development could be described as an increase in complexity. Starting with an individual cell, the growth of a multicellular organism can be divided into three phases – (i) Cell division – an increase in cell number as a result of mitosis and cell division; (ii) Cell enlargement – and irreversible increase in cell size as a result of uptake of water or the synthesis of living material; (iii) Cell differentiation – the specialization of cells; in its broad sense, the growth also includes this phase of cell development. Briefly mention the five phases of human development namely infancy, childhood, adolescence, adulthood, and senescence or late adulthood.

Chapter 3 Heredity and Common Genetic Disease

Chapter 3A Heredity:
Discussions should include the following with relevant examples: Members of a family share many similarities in appearance, such as height, eye color, and hair colour. People may also note that there are differences in the manner in which characteristics are inherited by offspring. Offsprings do not look exactly like their parents. An Austrian monk, Gregor Johann Mendel performed a series of simple experiments and discovered how heredity worked. Heredity is the transmission of characteristics or traits from one generation to another through reproduction. Sometimes alteration may occur in chromosome structure or number or there may be an alteration in a gene due to a change in DNA composition. This phenomenon is termed mutation. This permanent change in chromosome or DNA may result in a difference in the expression of characters, termed variation. A brief explanation of variation with suitable examples from human-free and attached ear lobe, roller, and normal tongue. Explain key terms associated with heredity with proper examples – (i) Characteristics or traits, (ii) Allele, (iii) Locus, (iv) Unit of inheritance (Factor/Gene), (v) Monohybrid and dihybrid Cross, (vi) Homozygous and heterozygous organisms, (vii) Hybridization, (viii) Pure and hybrid, (ix) Parental generation, (x) Filial generations (F,, F ), (xi) Dominant and recessive characteristics, (xii) Phenotype and genotype (Explain through sample cross). Mendel’s work on the pea plant is to be mentioned. Explanation of cross-pollination as practiced by Mendel (eg. removing another from a flower of a plant and transferring pollen grains from a flower of another plant to that flower with the help of a brush) with the help of proper diagrams. Reasons behind Mendel’s success to be mentioned. The seven pairs of contrasting characters as chosen by Mendel to be mentioned in tabular form with diagrams. Explanation of Mendel’s experiments on Heredity (Monohybrid and Dihybrid Cross) with examples from Pea plant and Guineapig using checkerboard. Explaining deduction of Mendel’s Laws (Law of Segregation and Law of Independent Assortment) with reference to pea plant and guineapig.

Chapter 3
Resistance and Rebellion: Characteristics and Analyses
The victory at Plassey (1757) gave the English East India Company political control of India. The imperialist interest of the company or the British colonial power led them to execute various exploitative measures. To tap the huge natural resources of the Indian forests they formed the Indian Forest Act of 1865 and 1878 thereby depriving the tribal population of their traditional rights in the forests of India and forcing them to rise in rebellion. The imposition of the high rate of land revenue, the breaking down of the economic structure of the country, the oppression and misrule both on the peasants and landlords and zamindars, and the introduction of the sun-set law, the Permanent Settlement Act resulted in various revolts. It was these uprisings, rebellions, and revolts that eventually gave rise to the political consciousness and nationalist outlook of the people of India. Examples – Chuar Rebellion, Wahabi Movement, Indigo Revolt, etc.

Chapter 4 Early Stages of Collective Action: Characteristics and Analyses
One hundred years after the battle of Plassey (1757) in the year 1857 a Great Revolt occurred due to the accumulation of discontent and grievances in the minds of the Indians towards their oppressive and imperialist Colonial rulers. The 19th century observed the growth of collective action in India which was manifested through the Revolt of 1857, the growth of associations, patriotic literature, and works of art like paintings. The collective organization and movements that took place in that period were predominantly against the British, against the age-old superstitions and to promote nationalism. There is a great deal of controversy among historians regarding the nature of the Great Revolt of 1857. Some British historians like Maleson, John Silly, John Keay, etc called it the Sepoy Mutiny which was supported by contemporary Indians like Akshay Kumar Dutta, Durgadas Banerjee, Dadabhai Naoroji, etc. J. B. Norton, Alexander Duff, Outram, Holmes, and even V. A. Smith and Karl Marx accepted the national character of the revolt or termed it a National Revolt. The revolutionary and nationalist thinker Vinayak Damodar Savarkar called it India’s First War of Independence, while R C. Joshi and others called it a National Struggle directed by the feudal lords. The English-educated Bengali intelligentsia being influenced by Western education and reforms of the colonial government did not support the sepoys. It was as a result of the Revolt of 1857, the English East India Company’s rule in India came to an end and power was transferred to the British crown. India was brought under the British crown by the Government of India Act of 1858. Queen Victoria’s famous proclamation was announced by Lord Canning at a grand durbar at Allahabad on 1st November 1858; Before the formation of the Indian National Congress in 1885 many associations were formed in different regions of India like Bombay, Madras, and especially in Bengal namely the Bangabhasa Prakashika Sabha, Landholders ’ society, Hindu Mela, Bharat Sabha, Poona Sarvajanik Sabha, Madras Mahajan Sabha etc.; To enlighten the people in nationalist ideas and patriotism a host of literary works were composed by Bankim Chandra (Anandamath), Rabindranath Tagore (Gora), and Swami Vivekananda (Bartaman Bharat). Their books played quite a significant role in arousing political awareness among the Indians. Mention must be made of the inspirational painting of ‘Bharat Mata’ by Abanindranath Tagore and the satirical sketches and cartoons (University Machine) by Gaganendranath Tagore in this context.

Chapter 5 Alternative Ideas and Initiatives
The social, religious, political, economic, and cultural ideas that developed in the first half of the 19th century underwent a great change and gave rise to new concepts and ideas in the second half of the 19th century. With the advent of Western education, social and political awareness started playing an important role in the minds of the Indian people and society. As a result, there was a drastic change in the thought process of the Indians and alternative ideas triumphed over the practiced ones. 19th century induced nationalism and ideas of national unity among the Indians which were further promoted with the development of the Indian press. Starting from the ‘Bengal Gazettee’ of Hicky (1780) to ‘Sambad Prabhakar’ of Iswarchandra Gupta (1831), newspapers helped generate knowledge and consciousness among the primarily urban people. The development of science and technology was limited during colonial rule. As a result, initiatives were taken by different notable Indians (like Mahendra Lal Sircar, Acharya Jagadish Chandra Bose, etc.) to develop scientific knowledge and research. It was the aim of the colonial government to produce Western-educated Indians who would only serve the need to rule the country. The Indians now started criticizing this colonial concept of education and thought of replacing it with alternative ideas of spreading education. The pioneering personality in this field was Rabindranath Tagore who subsequently formed, ‘Brahmacharyashram’ and ‘Visva Bharati at Shantiniketan, Bolpur.

Chapter 6 Peasant, Working Class, and Left Movements in 20th-Century India
The imperialist attitude of the British affected the peasant community in India strongly in the first half of the 20th Century who, being subjected to a lot of oppression and exploitation, rebelled against the landlords and the imperialist Government. The labour Movement in India which was much more organized aimed against the oppression and deprivation of the workers in the hands of the factory owners. The peasants did not play any significant role in the Anti-Partition Movement but they actively participated in the Non-cooperation Movement (1920), Civil Disobedience Movement (1930), and the Quit India Movement (1942). The working class played a significant role during the Anti-Partition Movement (1905) and organized several strikes against the mill and factory owners in the period. They also participated in the Non-cooperation Movement (1920) and Civil Disobedience Movement (1930). However, their participation in the Quit India Movement (1942) was limited.

Chapter 7 Movements Organised by Women, Students, and the Marginal People in the 20th Century
The 20th century saw the participation of women, students, and marginal people like the Dalits in organizing various movements. Women’s participation could be witnessed during the Anti-Partition Movement, the Non-cooperation Movement, the Civil Disobedience Movement, the Quit India Movement, and also in the armed revolutionary movement. Most of the anti-British movements during the 20th century reached a great dimension through the participation of the student community in India. They fearlessly took part in the Anti-Partition Movement, the Non-cooperation Movement, the Civil Disobedience Movement the Quit India Movement. The revolutionary group of students in Bengal, Bihar, Maharashtra, Punjab, and Uttar Pradesh made notable contributions in India’s struggle for freedom. The movement of the marginal class or the Dalits formed another important feature of the 20th-century movements.

Chapter 8 Post Colonial India Second Half of the 20th Century (1947-1964)
After 190 years of British domination, India won independence on 15th August 1947. But by the provision of the Indian Independence Act the native rulers had the choice to accede either to Pakistan or to India. This resulted in a lot of trouble and Sardar Vallabhbhai Patel, the first Home Minister of independent India was able to merge the native states into the Indian Union. However, Pakistan refused to accept the inclusion of Kashmir to India which resulted in a number of wars, tension between the two countries, and the creation of ‘Pakistan occupied Kashmir ’. The partition of India gave rise to the problems like communal riots and the issues related to the ‘Refugees’. Both the governments of India and Pakistan tried to solve the refugee Problem through the ‘Nehru-Liaquat’ Agreement of 1950. However, the influx of refugees to India continued even after this agreement. The linguistic policies adopted by the Nehru government after independence also created problems and ultimately the government had to concede to the demands of forming states on the basis of languages. By the State Reorganisation Act of 1956, the states of India were also reorganized. Till 1964, there were 14 recognized languages mentioned in the 8th schedule of our constitution. At present, there are 22 recognized languages. Hindi and English are recognized as the official languages of India.
