    NCERT Exemplar Class 11 Biology Chapter Details and Exercises

    Chapter 1: The Living World

    This chapter delves deeper into fundamental notions such as “What is Living?” and “What is Death?” Taxonomic Categories, Taxonomic Aids, and other topics are discussed. Variety abounds in the living world. Until now, millions of plant and animal species have been identified and documented, but there are yet millions more to be discovered.

    Taxonomic studies of numerous plant and animal species are useful in agriculture, forestry, industry, and for understanding our resources and diversity in general. Taxonomists have created a number of taxonomic aids to help an organism’s identification, naming, and categorization.

    Topics were covered

    What is living? Biodiversity; Need for classification; taxonomy and systematics; the concept of species and taxonomical hierarchy; binomial nomenclature; tools for the study of taxonomymuseums, zoological parks, herbaria, botanical gardens, keys for identification.

    Chapter 2: Biological Classification

    In this chapter, we’ll look at the characteristics of Kingdoms Monera, Protista, and Fungi of the Whittaker system of classification. In Chapters 3 and 4, the kingdoms Plantae and Animalia, also known as the plant and animal kingdoms, will be discussed separately. You’ll learn about Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae, Kingdom Animalia, Viruses, Viroids, and Lichens as part of the biological classification.

    Topics were covered

    Five kingdom classification; Salient features and classification of Monera, Protista, and Fungi into major groups; Lichens, Viruses, and Viroids.

    Chapter 3: Plant Kingdom

    We looked at the general classification of living species in the last chapter, which was based on Whittaker’s (1969) Five Kingdom classification, which included Monera, Protista, Fungi, Animalia, and Plantae. In this chapter, we’ll go through further classification within the Kingdom Plantae, also known as the ‘plant kingdom.’ You’ll also learn about Algae, Bryophytes, Pteridophytes, Gymnosperms, Angiosperms, Plant Life Cycles, and Generations Alternation.

    Topics were covered

    Salient features and classification of plants into major groups – Algae, Bryophyta, Pteridophyta, Gymnospermae, and Angiospermae (salient and distinguishing features and a few examples of each category): Angiosperms – classification up to class, characteristic features, and examples. Plantlife cycles and alternation of generations.

    Chapter 4: Animal Kingdom

    We see a variety of animals with various structures and forms when we glance around. With over a million animal species documented to date, the necessity for taxonomy becomes even more critical. Newly described species can also be assigned a systematic position thanks to categorization. It also covers topics like the Basis of Classification, Animal Classification, and more. In this chapter, students will learn a little about the animal kingdom.

    Topics were covered

    Basis of Classification; Salient features and classification of animals, non-chordates up to phyla level, and chordates up to class level (salient features and distinguishing features of a few examples of each category). (No live animals or specimens should be displayed in school.)

    Chapter 5: Morphology of Flowering Plants

    We discussed plant classification in chapters 2 and 3 based on morphological and other traits. Standard technical words and definitions are required for any effective attempt at classification and understanding of any higher plant (or, for that matter, any living entity). We also need to know about probable changes in different sections that occur as a result of plant adaptations to their environment, such as adaptations to varied habitats, protection, climbing, and storing. The root, stem, leaf, inflorescence, flower, fruit, seed, semi-technical description of a typical flowering plant, description of several major families, and more are all covered in Morphology of Flowering Plants.

    Topics were covered

    Morphology and modifications: Morphology of different parts of flowering plants: root, stem, leaf, inflorescence, flower, fruit, and seed. Description of families: Fabaceae, Solanaceae, and Liliaceae (to be dealt with along with the relevant experiments of the Practical Syllabus).

    Chapter 6: Anatomy of Flowering Plants

    The internal structure and functional organization of higher plants are discussed in this chapter. Anatomy is the study of a plant’s interior structure. Plants are made up of cells, which are organized into tissues, and tissues, in turn, are organized into various components of the plant. Monocots and dicots are anatomically distinct within angiosperms. Internal structures are also adaptable to a variety of settings. The Tissues, The Tissue System, Anatomy of Dicotyledonous and Monocotyledonous Plants, Secondary Growth, and other topics are covered.

    Topics were covered

    Anatomy and functions of different tissues and tissue systems in dicots and monocots. Secondary growth.

    Chapter 7: Structural Organisation in Animals

    The internal structure and functional organization of higher plants are discussed in this chapter. Anatomy is the study of a plant’s interior structure. Plants are made up of cells, which are organized into tissues, and tissues, in turn, are organized into various components of the plant. Monocots and dicots are anatomically distinct within angiosperms.

    Internal structures are also adaptable to a variety of settings. The Tissues, The Tissue System, Anatomy of Dicotyledonous and Monocotyledonous Plants, Secondary Growth, and other topics are covered.

    Topics were covered

    Animal tissues; Morphology, Anatomy, and functions of different systems (digestive, circulatory, respiratory, nervous, and reproductive) of an insect-cockroach (a brief account only).

    Chapter 8: Cell – The Unit of Life

    You can see both living and non-living things when you glance around. “What is it that makes an organism live?” you must have wondered. “What is it that an inanimate object lacks that a live thing possesses?” or “What is it that an inanimate object possesses that a living thing possesses?” The presence of the basic unit of life — the cell – in all living organisms is the answer. Cells make up every living thing. Unicellular organisms are those that are made up of only one cell. Others, like us, are multicellular organisms since they are made up of many cells.

    Topics were covered

    Cell theory and cell as the basic unit of life, structure of prokaryotic and eukaryotic cells; Plant cell and animal cell; cell envelope; cell membrane, cell wall; cell organelles – structure and function; endomembrane system- endoplasmic reticulum, ribosomes, Golgi bodies, lysosomes, vacuoles; mitochondria, plastids, microbodies; cytoskeleton, cilia, flagella, centrioles (ultrastructure and function); nucleus.

    Chapter 9: Biomolecules

    In our biosphere, there is a huge range of living species. How to Analyze Chemical Composition? is another topic covered in this chapter. Biomacromolecules, Proteins, Polysaccharides, Nucleic Acids, Protein Structure, Nature of Bond Linking Monomers in a Polymer, Dynamic State of Body Constituents – Metabolism, Metabolic Basis for Living, The Living State, Enzymes Students can learn more about these topics by consulting Infinity Learn’s NCERT Exemplar Solutions for Class 11 Biology Chapter 9 Biomolecules.

    Topics were covered

    Chemical constituents of living cells: biomolecules, structure, and function of proteins, carbohydrates, lipids, nucleic acids; the concept of metabolism; Enzymes – properties, enzyme action, factors, classification, Co-factors.

    Chapter 10: Cell Cycle and Cell Division

    Cells, and indeed all living creatures, have the ability to grow and reproduce. Every cell divides into two daughter cells, with each parental cell producing two daughter cells each time it divides. These newly generated daughter cells can expand and divide, resulting in the formation of a new cell population from the development and division of a single mother cell and its progeny.

    In other words, such growth and division cycles enable a single cell to expand into a complex with millions of cells. Other subtopics covered in the chapter include Cell Cycle, M Phase, Mitosis Significance, Meiosis Significance, and Meiosis Significance.

    Topics were covered

    Cell cycle, mitosis, meiosis, and their significance.

    Chapter 11: Transport in Plants

    Means of Transport, Plant-Water Relations, Long Distance Water Transport, Transpiration, Uptake and Transport of Mineral Nutrients, Phloem, and Transport: Flow from Source to Sink are some of the topics covered in the chapter Transport in Plants. Plants get a range of inorganic elements (ions) and salts from their environment, including water and soil.

    The vascular system of higher plants, which consists of the xylem and phloem, is responsible for translocation. Food (mainly sucrose) is transported from the source to the sink via the phloem. The pressure-flow hypothesis explains the translocation in the phloem.

    Topics were covered

    Movement of water, gases, and nutrients; cell to cell transport – diffusion, facilitated diffusion, active transport; plant-water relations, imbibition, water potential, osmosis, plasmolysis; long-distance transport of water – Absorption, apoplast, symplast, transpiration pull, root pressure, and guttation; transpiration, opening and closing of stomata; Uptake and translocation of mineral nutrients – Transport of food, phloem transport, mass flow hypothesis.

    Chapter 12: Mineral Nutrition

    This chapter is primarily concerned with inorganic plant nutrition, and we will look at the methods for identifying components that are required to plant growth and development, as well as the criteria for determining essentiality. We’ll also look at the role of important elements, their most common deficiency symptoms, and how these elements are absorbed. The importance and method of biological nitrogen fixation are also briefly discussed in the chapter Mineral Nutrition.

    Topics were covered

    Elementary idea of hydroponics as a method to study mineral nutrition; essential minerals, macro-and micronutrients and their role; Deficiency symptoms; Mineral toxicity; nitrogen metabolism, nitrogen cycle, biological nitrogen fixation.

    Chapter 13: Photosynthesis in Higher Plants

    Plants are the only source of sustenance for all animals, including humans. Green plants, often known as autotrophs, produce or rather synthesize the food they require through photosynthesis. Photosynthesis is a physicochemical process in which green plants use light energy to promote the synthesis of organic molecules.

    Photosynthesis is significant for two reasons: it is the foundation of all known food chains on the planet. It’s also in charge of green plants releasing oxygen into the atmosphere. The structure of the photosynthetic machinery, as well as the different reactions that convert light energy into chemical energy, are discussed in this chapter.

    Topics were covered

    Photosynthesis as a means of autotrophic nutrition; early experiments, site of photosynthesis, pigments involved in photosynthesis (elementary idea); photochemical and biosynthetic phases of photosynthesis; cyclic and non-cyclic photophosphorylation; chemiosmotic hypothesis; photorespiration; C3 and C4 pathways; Factors affecting photosynthesis.

    Chapter 14: Respiration in Plants

    The mechanism of cellular respiration, or the breakdown of dietary components within the cell to release energy, and the trapping of this energy for the creation of ATP, is discussed in this chapter. This chapter also delves into questions such as “Do Plants Breathe?” Glycolysis, Fermentation, Aerobic Respiration, The Respiratory Balance Sheet, Amphibolic Pathway, Respiratory Quotient, Glycolysis, Fermentation, Aerobic Respiration, The Respiratory Balance Sheet, The Respiratory Balance Sheet, The Respiratory Balance Sheet, The Respiratory Balance Sheet, The key principles of this chapter, Respiration in Plants, are discussed in simple language to help Class 11 students understand them.

    Topics were covered

    Exchange of gases; do plants breathe; cellular respiration – glycolysis, fermentation (anaerobic), TCA cycle and electron transport system (aerobic); energy relations – number of ATP molecules generated; amphibolic pathways; respiratory quotient.

    Chapter 15: Plant Growth and Development

    In Chapter 5, we looked at the organization of a flowering plant. We’ll look at some of the components that govern and control these developmental processes in this chapter. The plant is affected by both intrinsic (internal) and extrinsic (external) forces.

    Growth Differentiation, Dedifferentiation, Redifferentiation, Development, Plant Growth Regulators, Photoperiodism, Vernalization, and other subtopics are among the others. Plant Growth and Development answers have been prepared by Infinity Learn highly experienced professors to help students ace the final test.

    Topics were covered

    Seed germination; characteristics, measurements, and phases of plant growth, growth rate; conditions for growth; differentiation, differentiation, and redifferentiation; Sequence of developmental processes in a plant cell; growth regulators – auxin, gibberellin, cytokinin, ethylene, ABA; seed dormancy; vernalization; photoperiodism.

    Chapter 16: Digestion and Absorption

    Food is one of the most basic needs of all living things. Carbohydrates, proteins, and fats are the three main components of the human diet. In modest amounts, vitamins and minerals are also necessary. Food supplies energy as well as organic resources for tissue growth and repair.

    Water plays a crucial function in metabolic processes and also helps to keep the body hydrated. Our bodies are unable to use biomacromolecules in their natural state. In the digestive system, they must be broken down and turned into simple compounds.

    Digestion is the mechanical and biological conversion of complex dietary molecules to simple absorbable forms, which is carried out by our digestive system. To help students comprehend these ideas, the chapter Digestion and Absorption provides a brief explanation.

    Topics were covered

    Alimentary canal and digestive glands, the role of digestive enzymes and gastrointestinal hormones; Peristalsis, digestion, absorption and assimilation of proteins, carbohydrates and fats; egestion; nutritional and digestive disorders – indigestion, constipation, vomiting, jaundice, diarrhea.

    Chapter 17: Breathing and Exchange of Gases

    As you may recall, organisms use oxygen to derive energy by breaking down simple molecules such as glucose, amino acids, fatty acids, and so on. The foregoing catabolic events also emit carbon dioxide, which is toxic. As a result, oxygen must be continuously supplied to the cells, and the carbon dioxide created by the cells must be expelled. Breathing is the process of exchanging oxygen from the atmosphere with carbon dioxide produced by the cells. It’s also known as breathing.

    Topics were covered

    Introduction to respiratory organs in animals; Respiratory system in humans; Mechanism of breathing and its regulation in humans – exchange of gases, transport of gases and regulation of respiration, respiratory volumes; Disorders related to respiration – asthma, emphysema, occupational respiratory disorders.

    Chapter 18: Body Fluids and Circulation

    We’ve learned that nutrition, oxygen, and other necessary elements must be delivered to all living cells. Furthermore, in order for tissues to function properly, waste or toxic chemicals must be removed on a regular basis. In most higher species, including humans, blood is the most widely used bodily fluid.

    Lymph, another bodily fluid, aids in the movement of specific chemicals. We’ll look at the composition and properties of blood and lymph (tissue fluid) in this chapter, as well as the mechanics of blood circulation.

    Topics were covered

    Composition of the blood, blood groups, coagulation of blood; composition of lymph and its function; circulatory pathways; human circulatory system – Structure of human heart and blood vessels; cardiac cycle, cardiac output, ECG; double circulation; regulation of cardiac activity; disorders of the circulatory system – hypertension, coronary artery disease, angina pectoris, heart failure.

    Chapter 19: Excretory Products and their Elimination

    Human Excretory System, Urine Formation, Tubule Function, Filtrate Concentration Mechanism, Kidney Function Regulation, Micturition, Role of Other Organs in Excretion, Excretory System Disorders, and more are covered in this chapter.

    Topics were covered

    Modes of excretion – ammonotelism, ureotelism, uricotelism; human excretory system – structure and function; urine formation, osmoregulation; regulation of kidney function – renin-angiotensin, atrial natriuretic factor, ADH, diabetes insipidus; micturition; the role of other organs in excretion; disorders – uremia, renal failure, renal calculi, nephritis; dialysis and artificial kidney, a kidney transplant.

    Chapter 20: Locomotion and Movement

    One of the most important characteristics of living things is movement. Animals and plants can move in a variety of ways. Locomotion is the term for such voluntary movements. Locomotory movement includes walking, running, climbing, flying, and swimming.

    Structures impacting locomotion do not need to be distinct from those affecting other types of movement. Animal movement differs depending on their habitats and the demands of the scenario. Finding food, refuge, a mate, good breeding grounds, favorable climatic conditions, or escaping from predators are among the reasons for locomotion.

    Topics were covered

    Types of movement – amoeboid, ciliary, flagellar, muscular; types of muscles; skeletal muscle, contractile proteins, and muscle contraction; skeletal system and its functions; joints; disorders of muscular and skeletal systems – myasthenia gravis, tetany, muscular dystrophy, arthritis, osteoporosis, gout.

    Chapter 21: Neural Control and Coordination

    The process by which two or more organs interact and complement one another’s functions is known as coordination. The brain and endocrine systems in our bodies work together to coordinate and integrate all of the organs’ operations so that they work in unison. We will learn about the human neurological system, neural coordinating processes such as nerve impulse transmission, impulse conduction across a synapse, and the physiology of reflex response in this chapter.

    Topics were covered

    Neuron and nerves; Nervous system in humans – the central nervous system and peripheral nervous system; generation, conduction, and transmission of nerve impulse; reflex action; sensory perception; sense organs; elementary structure and functions of eye and ear.

    Chapter 22: Chemical Coordination and integration

    We already know that the neural system allows for quick point-to-point coordination between organs. Neural coordination is quick but fleeting. Because nerve fibers do not innervate all cells in the body and cellular processes must be constantly regulated, a unique level of coordination and integration is required.

    Hormones are responsible for this function. The nervous and endocrine systems work together to coordinate and regulate the body’s physiological processes. The NCERT Exemplar Solutions from Infinity Learn can help students learn chemical coordination and integration more effectively.

    Topics were covered

    Endocrine glands and hormones; human endocrine system – hypothalamus, pituitary, pineal, thyroid, parathyroid, thymus, adrenal, pancreas, gonads; hormones of heart, kidney, and gastrointestinal tract; mechanism of hormone action (elementary idea); the role of hormones as messengers and regulators, hypo – and hyperactivity and related disorders; dwarfism, acromegaly, cretinism, goiter, exophthalmic goiter, diabetes, Addison’s disease.

    Note: Diseases related to all the human physiological systems to be taught in brief. Due to the vast amount of information contained in each notion, learning about these topics may be intimidating academically. The experience becomes effective and interesting with these well-developed study recommendations.

    How to Use NCERT Exemplar Solutions for Class 11 Biology in Board and Competitive Exams?

    Biology is a discipline that teaches us everything there is to know about the natural world. It, like other scientific disciplines, uses observation, experimentation, and documentation to try to explain various phenomena, events, or species. Here are some helpful hints for studying biology.

    • Drawing

    The NCERT Class 11 Biology syllabus includes a lot of diagrams. However, you will not have much time during the exam to draw neatly or clearly, which may prohibit you from receiving the marks you require to pass the exam.

    As a result, practice some components of the essential schematics beforehand, such as shading and texturing. You will stand out among your classmates if you do this. Now, this may take some time to learn and master, but the payoff is well worth the effort.

    • Breaking down Information

    You may find it difficult to remember everything due to the sheer volume of data. That is why you should establish an information chunking strategy, in which the knowledge is broken down into small chunks to make it easier for the student to understand. This is particularly helpful since it reduces the cognitive burden, which in turn reduces mental tiredness. The way you divide the data is entirely up to you and your talents.

    • Making Note

    Although everyone is aware of this, not everyone puts it into practice. This strategy is underappreciated, although it is quite useful in examinations. Make a mental note of the key points that the teacher makes whenever you attend a lecture.

    This procedure stimulates your thoughts and makes it easier to recall knowledge. Additionally, this is an important tool to employ when revising for your exam. Because you prepared these notes, you will have an easier time understanding and remembering the information than if you used a textbook.

    NCERT Exemplar Solutions, notes, question papers, and worksheets for subjects such as Mathematics, Physics, and Chemistry may be found here. We also have materials to help you prepare for competitive exams.
