Chapter 5: Morphology of Flowering Plants
In chapters 2 and 3, we talked about the classification of plants based on morphological and other characteristics. For any successful attempt at classification and understanding any higher plant (or, for that matter, any living organism), we need to know standard technical terms and definitions. We also need to know about the possible variations in different parts, found as adaptations of the plants to their environment, e.g., adaptations to various habitats for protection, climbing, and storage. Morphology of Flowering Plants also explains topics such as the root, stem, leaf, inflorescence, flower, fruit, seed, semi-technical description of a typical flowering plant, description of some important families and more.
Topics Covered in Class 11 Biology Chapter 5 Morphology of Flowering Plants:
Morphology of different parts of flowering plants: root, stem, leaf, inflorescence, flower, fruit and seed; Description of family Solanaceae.

Chapter 6: Anatomy of Flowering Plants
This chapter introduces the internal structure and functional organisation of higher plants. The study of the internal structure of plants is called anatomy. Plants have cells as their basic unit. Cells are organised into tissues, and in turn, the tissues are organised into various parts of the plant. Within angiosperms, the monocots and dicots are anatomically different. Internal structures also show adaptations to diverse environments. The chapter includes topics such as The Tissues, The Tissue System, Anatomy of Dicotyledonous and Monocotyledonous Plants, Secondary Growth, and more.
Topics Covered in Class 11 Biology Chapter 6 Anatomy of Flowering Plants :
Anatomy and functions of tissue systems in dicots and monocots.

Chapter 7: Structural Organisation in Animals
In the preceding chapters, we came across a large variety of organisms, both unicellular and multicellular, of the animal kingdom. In unicellular organisms, all functions like digestion, respiration and reproduction are performed by a single cell. In the complex body of multicellular animals, the same basic functions are carried out by different groups of cells in a well-organised manner. All complex animals are made up of only four basic types of tissues. These tissues are organised in specific locations to form organs, such as the stomach, lungs, heart and kidney. Students can understand the structural organisation in animals and score well in the exam by referring to the solutions available on BYJU’S.
Topics Covered in Class 11 Biology Chapter 7 Structural Organisation in Animals:
Morphology, Anatomy and functions of different systems (digestive, circulatory, respiratory, nervous and reproductive) of frog.

Chapter 8: Cell The Unit of Life
When you look around, you see both living and non-living things. You must have asked yourself – “What is it that makes an organism living?” or, “What is it that an inanimate object does not have that a living thing has?” The answer to this is the presence of the basic unit of life – the cell in all living organisms. All organisms are composed of cells. Some are composed of a single cell and are called unicellular organisms. In contrast, others, like us, are composed of many cells and are called multicellular organisms.
Topics Covered in Class 11 Biology Chapter 8 Cell The Unit of Life:
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, golgi bodies, lysosomes, vacuoles, mitochondria, ribosomes, plastids, microbodies; cytoskeleton, cilia, flagella, centrioles (ultrastructure and function); nucleus.

Chapter 10: Cell Cycle and Cell Division
Growth and reproduction are characteristics of cells, indeed of all living organisms. All cells reproduce by dividing into two, with each parental cell giving rise to two daughter cells each time they divide. These newly-formed daughter cells can themselves grow and divide, giving rise to a new cell population that is formed by the growth and division of a single parental cell and its progeny. In other words, such cycles of growth and division allow a single cell to form a structure consisting of millions of cells. Other subtopics mentioned in the chapter are Cell Cycle, M Phase, Significance of Mitosis, Meiosis, and Significance of Meiosis.
Topics Covered in Class 11 Biology Chapter 10 Cell Cycle and Cell Division:
Cell cycle, mitosis, meiosis and their significance

Chapter 11: Transport in Plants
Topics in the chapter Transport in Plants include Means of Transport, Plant-Water Relations, Long Distance Transport of Water, Transpiration, Uptake and Transport of Mineral Nutrients, Phloem, and Transport: Flow from Source to Sink. Plants obtain a variety of inorganic elements (ions) and salts from their surroundings, especially from water and soil. In higher plants, there is a vascular system comprising xylem and phloem, responsible for translocation. Phloem is responsible for the transport of food, (primarily) sucrose from the source to the sink. The translocation in phloem is explained by the pressure-flow hypothesis.

Chapter 13: Photosynthesis in Higher Plants
All animals, including human beings, depend on plants for their food. Green plants make or rather synthesise the food they need through photosynthesis and are therefore called autotrophs. Green plants carry out ‘photosynthesis’, a physicochemical process which uses light energy to drive the synthesis of organic compounds. Photosynthesis is important for two reasons: it forms the basis for all known food chains on earth. It is also responsible for the release of oxygen into the atmosphere by green plants. This chapter focuses on the structure of the photosynthetic machinery and the various reactions that transform light energy into chemical energy.
Topics Covered in Class 11 Biology Chapter 13 Photosynthesis in Higher Plants:
Photosynthesis as a means of autotrophic nutrition; 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 16: Digestion and Absorption
Food is one of the basic requirements of all living organisms. The major components of our food are carbohydrates, proteins and fats. Vitamins and minerals are also required in small quantities. Food provides energy and organic materials for growth and repair of tissues. The water we take in plays an important role in metabolic processes and also prevents dehydration of the body. Biomacromolecules in food cannot be utilised by our body in their original form. They have to be broken down and converted into simple substances in the digestive system. This process of conversion of complex food substances to simple absorbable forms is called digestion and is carried out by our digestive system through mechanical and biochemical methods. These concepts are briefly explained in the chapter Digestion and Absorption to help students understand them effectively.

Chapter 17: Breathing and Exchange of Gases
As you have read earlier, oxygen is utilised by organisms to indirectly break down simple molecules like glucose, amino acids, fatty acids, etc., to derive energy to perform various activities. Carbon dioxide, which is harmful, is also released during the above catabolic reactions. It is, therefore, evident that oxygen has to be continuously provided to the cells and carbon dioxide produced by the cells has to be released. This process of exchange of oxygen from the atmosphere with carbon dioxide produced by the cells is termed breathing. It is also known as respiration.
Topics Covered in Class 11 Biology Chapter 17 Breathing and Exchange of Gases:
Respiratory organs in animals (recall only); Respiratory system in humans; mechanism of breathing and its regulation in humans – exchange of gases, transport of gases and regulation of respiration, respiratory volume; disorders related to respiration – asthma, emphysema, occupational respiratory disorders.

Chapter 18: Body Fluids and Circulation
We have learnt that all living cells have to be provided with nutrients, oxygen and other essential substances. Also, the waste or harmful substances produced have to be removed continuously for the healthy functioning of tissues. Blood is the most commonly used body fluid in most of the higher organisms, including humans. Another body fluid, lymph, also helps in the transport of certain substances. In this chapter, we shall explore the composition and properties of blood and lymph (tissue fluid) and the mechanism of circulation of blood is also explained herein.

Chapter 20: Locomotion and Movement
Movement is one of the significant features of living beings. Animals and plants exhibit a wide range of movements. Such voluntary movements are called locomotion. Walking, running, climbing, flying, and swimming are all forms of locomotory movement. Locomotory structures need not be different from those affecting other types of movements. Methods of locomotion performed by animals vary with their habitats and the demand of the situation. Locomotion is required for various reasons, such as finding food, shelter, mate, suitable breeding grounds, favourable climatic conditions, or to escape from predators.
Topics Covered in Class 11 Biology Chapter 20 Locomotion and Movement:
Types of movement – ciliary, flagellar, muscular; 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
Coordination is the process through which two or more organs interact and complement the functions of one another. In our body, the neural system and the endocrine system jointly coordinate and integrate all the activities of the organs so that they function in a synchronised fashion. In this chapter, we will learn about the neural system of humans, mechanisms of neural coordination like transmission of nerve impulses, impulse conduction across a synapse and the physiology of reflex action.
Topics Covered in Class 11 Biology Chapter 21 Neural Control and Coordination:
Neuron and nerves; Nervous system in humans – central nervous system; peripheral nervous system and visceral nervous system; generation and conduction of nerve impulse

Chapter 22: Chemical Coordination and integration
We have already learnt that the neural system provides point-to-point rapid coordination among organs. Neural coordination is fast but short-lived. As the nerve fibres do not innervate all cells of the body and the cellular functions need to be continuously regulated, a special kind of coordination and integration has to be provided. This function is carried out by hormones. The neural system and the endocrine system jointly coordinate and regulate the physiological functions in the body. Students can learn chemical coordination and integration more efficiently by referring to NCERT Solutions from BYJU’S.
Topics Covered in Class 11 Biology Chapter 22 Chemical Coordination and Integration:
Endocrine glands and hormones; human endocrine system – hypothalamus, pituitary, pineal, thyroid, parathyroid, adrenal, pancreas, gonads; mechanism of hormone action (elementary idea); role of hormones as messengers and regulators, hypo – and hyperactivity and related disorders; dwarfism, acromegaly, cretinism, goitre, exophthalmic goitre, diabetes, Addison’s disease.

How to utilise Class 11 Biology NCERT Solutions for Board and Competitive exams?
Biology is a subject that tells us all about the natural world. Just like the other disciplines of science, it tries to explain the various phenomenon, events, or organisms with the help of observation, experimentation and documentation. Here are a few tips you need to learn to study biology.
Diagrams are a prominent part of NCERT Class 11 Biology syllabus. In the exam, though, you will not have much time to draw neatly or clearly, and this, in turn, might prevent you from scoring well in the exam. Therefore, practise the relevant diagrams paying attention to aspects such as shading and texturing beforehand. Doing this will make you stand out from your fellow students. Now, this might take some time to develop and get good at, but the reward is worth it.
- Breaking down Information
The sheer magnitude of information might make it hard for you to remember everything. That is why you need to develop a technique called information chunking, where the information is broken down into small chunks, making it easier for the student to process the information. This is very effective because the cognitive load is reduced, and this, in turn, slows down mental fatigue. How you split the information is entirely dependent on you and your abilities.
- Note Taking
Everyone already knows this, but not everyone implements it. This technique is underrated but incredibly helpful from an examination perspective. Whenever you are attending a lecture, make sure you note down the crucial points that the teacher says. This process stimulates your thinking, and you can recall information more easily. Furthermore, this is an essential tool when revising for your exam. Since you prepare these notes, you will find it easier to comprehend and recall the information.
