Chapter 1: Life Processes

Life processes, as the name suggests, are the processes going on during the life of a living organism. The processes that function together for the maintenance of life are called life processes. This chapter explains the different processes going on in a living organism. A living organism undergoes many life processes like nutrition, respiration, digestion, transportation, excretion, circulation of blood and reproduction. It also includes the life processes of unicellular and multicellular organisms. These processes are very vital for an organism to stay alive and to maintain the proper functioning of the body. This chapter also covers the metabolism of plants’ life cycle and structure. These are the series of processes that ensures that the organism is alive.

Chapter 2: Control and Coordination

The human body is a complex machine which performs various functions to keep the body fit and fine. The working together of various organs of the body of an organism in a controlled manner to produce an appropriate reaction to a stimulus is called coordination. The control and coordination of all the organs of an organism are done by the central nervous system of the body. This chapter explains the working of the nervous system and its consequences. It also gives a detailed picture of the structure of neurons, tropic movements, reflux actions, hormones, reflex action, the human brain and also about types of nerves. These topics are explained diagrammatically and include all the pinpoints of the concepts.

Chapter 3: How Do Organisms Reproduce

Life on this planet, earth, is from hundreds of generations ago and will continue for hundreds of generations. This continuity of generations is due to the biological process called reproduction. Reproduction is defined as the process by which an organism gives birth to its young ones. This chapter gives us an idea about the different classes of reproduction, that is, sexual reproduction and asexual reproduction. It gives a detailed description of the reproduction process taking place in plants as well as animals, the process of pollination taking place in plants,  measures to control the population, the fertilisation process and the menstrual cycle in females etc.

Chapter 4: Heredity and Evolution

The process by which the features of an organism are passed on from one generation to another is called heredity. This chapter gives us a brief idea of how the evolution of organisms takes place. The experiment of Gregor Johann Mendel, known as the ‘Father of Genetics’, is described in detail. Topics such as heredity, genes, evolution and their classification help students to understand the concepts in detail. The theories of evolution, its types and laws of inheritance are all described in the chapter. Heredity and Evolution is a vast topic and is covered in this chapter in a shortened and easy manner. It also provides a wide range of examples of different kinds of heredity and evolution, explains how the genes are carried to the next upcoming generation and how human life has evolved over the years.

Chapter 5: Our Environment

The chapter, Our Environment, includes the different types of components present in our environment. It gives us detailed descriptions of the ecosystem, food chain, food web and energy transformation from one organism to another. We will also learn about the different hazards happening in the environment. The environmental hazards include different kinds of pollution, global warming, and about species getting extinct from the planet. This chapter also explains the consequences of various kinds of pollution and how to control and prevent them. In general, it gives us an idea of how today’s young generation is exploiting the environment and how to deal with it.

Chapter 6: Management of Natural Resources

The chapter Management of Natural Resources focuses on the sustainable development of natural resources. It gives ideas on the conservation of natural resources, wildlife, forest and other natural resources. The resources which cannot be gained back are called natural resources. The chapter mainly deals with the control of water pollution and the importance of saving water. Water being the universal solvent, is on the verge of extinction. Hence, this chapter has given us ideas on the Ganga action plan, construction of dams, preserving water and rainwater harvesting. Besides, it highlights the importance of natural resources like coal and petroleum and how to use these resources judiciously and conserve them.
