This book contains six chapters of biology that are:
Chapter 1: Life Processes
Chapter 2: Control and Coordination
Chapter 3: How do Organisms Reproduce?
Chapter 4: Heredity and Evolution
Chapter 5: Our Environment
Chapter 6: Management of Natural Resources

Life Processes:

The first chapter of the book "Life Processes" revolves around the processes inside the animal and the plant body to keep it functioning efficiently. There are mainly five kinds of processes: nutrition, respiration, digestion, transportation, and excretion. All of these are required for the proper functioning of the human body, and if one of the processes is damaged, then the entire system slowly deteriorates, which can be fatal. Along with the human, animal, and plant processes, it also speaks about the processes that occur in unicellular organisms to keep them alive. This is one of the important chapters from which the students learn about the various systems that function inside the body and the importance of healthy nutrition so that energy can be provided for the unhindered functioning of all the organ systems. The chapter explains the process of nutrition for the human body, which depends on digestion and respiration. The food taken in is digested utilizing various enzymes in the body. The digestion breaks down the food into various simple compounds absorbed by the cells, and the respiration process provides the oxygen required to burn these simpler compounds to provide energy. The transportation of the body is done through the circulatory systems. The circulatory system is responsible for the oxygen circulation in the entire body, thus indirectly providing energy to the cells in the entire body. Finally, excretion is the process by which the waste is ejected from the body and doesn't accumulate to prove toxic for us.

Control and Coordination:

The second chapter of the book " Control and Coordination" is all about the complicated functions that work in a controlled manner to keep the body stable. A systematic process where all the body's organs work systematically to produce reactions to the actions is known as coordination. The book gives an insight into how the Central Nervous System controls the various organs of our body. The chapter also highlights how the nervous system works inside our body and our body's side effects if the nervous system gets damaged. From the chapter, the students also get a detailed idea of other important topics like the structure of a neuron, hormones involved in transmitting the message through a neuron, reflex action, tropic movements, the human brain, and different nerves. The chapter explains the various parts of the neuron along with the functions of these elements. It further elaborates the essence of specific hormones in transmitting the message and how they are essential in jumping the synaptic gap. The chapter digs deep into the concept of the brain. It talks in detail about the organ that controls it all. The brain is divided into three parts- the cerebrum, the cerebellum and medulla oblongata. The brain extends into the brain stem below the medulla, connecting the brain to the spinal cord. The spinal cord controls many involuntary functions, and all the motor reflexes originate in the spinal cord.

How do Organisms Reproduce?:

This chapter in the book " How do Organisms Reproduce?" introduces the concept of reproduction. It gives detailed information on the process of reproduction in animals and reproduction in plants. The chapter deals with both types of reproduction which involves sexual reproduction and asexual reproduction in its subject matter. The chapter talks about the mode of reproduction used in unicellular organisms. It discusses the method of fission which is seen in amoeba, where a single amoeba breaks into two. Another unicellular organism that has been discussed in the chapter is the Hydra which reproduces by the process called budding. The chapter further goes into the domain of asexual reproduction by telling the students about vegetative propagation and artificial propagation. The chapter also talks about sexual reproduction in plants, with the example of a flower having both the male and the female parts.

Furthermore, the chapter sheds some light on animal reproduction with an emphasis on human reproduction. This chapter introduces students to a very important concept of Heredity. Heredity is one of the important topics on which research is still ongoing. Moreover hence, students learn very basic level information on this topic.

Heredity and Evolution:

The fourth chapter of the book "Heredity and Evolution" is very interesting as it deals with the concept of genes, heredity, and evolution. The chapter is divided into two sections of genetics and evolution. Students learn about heredity that is the passing of features from one generation to the other. Concepts like variation (which ensures the continuity of a species when sudden environmental change takes place) and mutation are discussed. The cell division is talked about at length, discussing both the mitotic and meiotic division.

Furthermore, students are also introduced to the three laws based on which Gregor Johann Mendel, the father of Genetics, carried out his pea experiment. The chapter deals with the monohybrid and dihybrid cross. The concept of genes and alleles is also covered in the chapter. Heredity and evolution both are topics of a wide range. However, here, they are presented and compactly to understand the topics easily. This chapter is a geist on how human life has evolved and the information carried through genes from one generation to another.

Our Environment:

The second last chapter of the book " Our Environment" is crucial as it deals with the different components of nature that affect our living. If one of these components gets exhausted, then it brings an imbalance to our entire ecosystem. From this lesson, the students get a brief idea of matters like an ecosystem, food chains, food webs, and energy transformation from one organism to another. From this chapter, issues like environmental hazards due to increasing environmental pollution are also explained. It also informs the students about the consequences of the world if the pollution keeps on increasing.

Management of Natural Resources:

The sixth and last chapter of the book " Management of Natural Resources" educates the students on how natural resources, especially non-renewable can be conserved. It concentrates on the development of resources through sustainable methods. An idea of conserving natural resources like forests, wildlife, etc., is imparted to the students. Generally, the resources that cannot be gained back is called natural resource. This chapter points out how pollution of water can be controlled, and water wastage can be stopped. This chapter also brings Ganga Action Plan to student's notice. Moreover, various other ways of conserving water like dams, water preservation and rainwater harvesting have been discussed. This chapter separately highlights the non-renewable resources like coal and petroleum that are on the verge of extinction as they are non-renewable resources.

The main aim of the chapter is to educate the young minds and make them aware of our current environmental scenarios so that they start conserving natural resources right from a very young age and grow up to be responsible citizens.
