Chapter 1: The Living World 

This chapter introduces the learner to a wide range of natural flora and fauna. The students get an introduction to the concept of living and its meaning. The chapter then goes on to discuss taxonomic groups and assistance and then, the extremely essential topic of genus and species categorization is introduced to students. They are guided into the fascinating realm of living beings, where they learn previously undisclosed facts about their environment and habits. They're also taught about biodiversity and why it's so vital to preserve it. This is a virtue that all youth must possess in this day and age, and this chapter guarantees that it is instilled in them.

Chapter 2: Biological Classification

This chapter takes the learner further into the biological categorization. The categorization of the five kingdoms is described in a clear and easy-to-understand way. Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae, and Kingdom Animalia are among the kingdoms that are discussed in this chapter. Students will also study earlier categorization techniques employed by experts such as Aristotle and Linnaeus, as well as how the system has developed over time.

Chapter 3: Plant Kingdom

In this chapter, the pupils delve into the specifics of the world as it has been classified thus far. They study the plant kingdom's additional categorization in order to make it easier to study. They are exposed to new words such as Gymnosperms, Angiosperms, and so on throughout this lesson. They also learn about the plant life cycle and generational change. At the end of this chapter, students will have a thorough understanding of the natural environment, features, and physiology of the complex creatures known as plants.

Chapter 4: Animal Kingdom

This chapter focuses on the most significant kingdom, kingdom Animalia. Despite variations in shape and structure, there are essential characteristics that allow us to categorize them easily.

Any worthwhile attempt at categorization and viewing of any higher plant (or, in the case of living organisms, any live creature), necessitates the knowledge of standard technical terminology and definitions. We also need to consider the potential differences in various components discovered as plant adaptations to their environment, such as adaptations to diverse habitats, for protection, climbing, and storing. This chapter also explains topics such as the root, stem, leaf, inflorescence, flower, fruit, seed, semi-technical description of a typical flowering plant, and also discusses several major plant families.

Chapter 6: Anatomy of Flowering Plants

The internal structure and functional connection of higher plants are presented in this chapter. Plants contain cells as their building block, and the cells are coordinated into tissues, which are coordinated into different parts of the plant. The monocots and dicots are anatomically distinct within angiosperms. Internal structures, too, exhibit changes in response to diverse circumstances. This chapter includes topics such as The Tissues, The Tissue System, Anatomy of Dicotyledonous and Monocotyledonous Plants, Secondary Growth, and the list goes on. 

Chapter 7: Structural Organisation in Animals

Students have previously studied a wide range of living organisms, both unicellular and multicellular. They will be familiar by now that multicellular organisms, unlike unicellular organisms, have tissues with well-organized cells that perform various activities.

Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis are some of the stages they learn about in the cell cycle. Unit 3: Cell Structure and Functions comes to a close with this chapter. It carries a 9 percent weightage in NEET and 15 points in the final exam.

Chapter 11: Transport in Plants

Because plants, unlike mammals, lack motor capabilities, they must rely on the soil for nourishment and their roots to absorb it. As a result, plants have evolved a complex transportation system including Xylem and Phloem. In this chapter, the student learns about concepts such as imbibing, plasmolysis, and osmosis. They learn about active transport, and transpiration, among other topics. Refer to NCERT Biology Class 11 PDF in Hindi for a better understanding of this chapter.  

Chapter 12: Mineral Nutrition

Students learn to recognize the various minerals required for a plant's development and function in this chapter. They study what qualifies a mineral as necessary, as well as the mineral's mode of transport and absorption process. They also learn about the deficiency symptoms that indicate a lack of such minerals, giving them a more holistic perspective on the subject. They are also given a basic overview of nitrogen fixation and its importance.

Chapter 13: Photosynthesis in Higher Plants

Plants are the only source of sustenance for all creatures, including humans. Green plants, which are known as autotrophs, produce or arrange the food they require through photosynthesis. Photosynthesis is a physicochemical cycle in which light energy is used to promote the mixing of organic mixtures in green plants. Photosynthesis is crucial for two reasons: it shapes the reason for all realized food chains on the planet, and it forms the reason for all realized food chains on the planet. The architecture of photosynthetic hardware is discussed in this chapter, as well as the many reactions that convert light energy into chemical energy.

Chapter 14: Respiration in Plants

Till now, students will be familiarized with the fact that plants conduct two major functions: photosynthesis and respiration. Through this chapter, the pupils are introduced to the latter in this chapter. Aerobic and anaerobic respiration, glycolysis, fermentation, the electron transport system, and the tricarboxylic acid cycle are some of the new terminologies and concepts they will encounter.

Chapter 15: Plant Growth and Development

The students will focus on the numerous internal and extrinsic elements that influence a plant's growth and development in this chapter. They will study the plant development stages, growth regulators, differentiation, dedifferentiation, redifferentiation, Vernalization, and seed dormancy, among other things. They also learn about plant hormones and their role in plant growth and development. Unit 4: Plant Physiology comes to a close with this chapter. It carries a 6% weightage in NEET and is worth 18 marks in the final Biology examination.

In addition, the students are also taught about several most common respiratory disorders and their causes. 

Chapter 18: Body Fluids and Circulation

All living cells require nutrition, oxygen, and other fundamental components, as already studied in the previous chapters. Furthermore, waste or hazardous chemicals must be removed on a regular basis in order for tissues to function properly. Blood is the most often used bodily fluid in the vast majority of higher species, including humans. Lymph, another bodily fluid, also aids in the transfer of particular chemicals. In this chapter, we'll look at the organization and characteristics of blood and lymph (tissue fluids), as well as the method of blood dispersion.

Chapter 19: Excretory Products and their Elimination

Given that the students had recently dealt with gaseous waste in the previous chapter, it is logical that they would be interested in the removal of solid and liquid waste created by metabolic processes or excess intake. Therefore, this chapter focuses on the excretory system in humans. Students learn about the excretory system's many components, including the auxiliary organs. They learn about the process of urine production and kidney function control and also learn about various kidney diseases.

Chapter 20: Locomotion and Movement

One of the most important characteristics of living organisms is movement. Animals and plants move in a variety of ways. Locomotion refers to such voluntary motions. Large kinds of locomotory activities include strolling, running, climbing, flying, and swimming. Locomotory structures do not have to be distinctive in comparison to those affecting other types of motions. Animal movement techniques evolve in response to their environments and circumstances. Locomotion is required for a variety of reasons, including finding food, cover, a mating partner, suitable breeding grounds, optimal climatic conditions, and evading hunters.

Chapter 21: Neural Control and Coordination

Through this chapter, we learn that coordination is the process through which at least two organs interact and augment each other's components. The neurological framework and the endocrine framework in our body work together to coordinate and include all organ activities so that they operate in unison. The brain architecture of humans, neural coordination tools such as nerve impulse transmission, impulse conduction across a synapse, and the physiology of reflex action are all covered in this chapter. 

Chapter 22: Chemical Coordination and integration

This chapter discusses the endocrine and exocrine glands that exist in organisms. The human endocrine system, the hormones released by it, the activities of these hormones, and the diseases induced by excess or deficiency of the same are all given special attention. Students learn about the mechanism of hormone action as well as the feedback mechanism that controls hormone production. This chapter brings Unit 5, Human Physiology, to a close. It carries a weightage of 20% in NEET and 18 points in the final exam.
