The Central Board of Secondary Education does not bifurcate the subject of science until secondary school. As such one may find the inclusion of Physics, Chemistry and Biology in a single subject, and a single book that is Science. Science as a whole not only makes the subject less complicated but also creates a sense of relief unburdening the students with unnecessary complex topics. Having said that, CBSE Class 10 Science has clearly made a distinction between the chapters and one can easily understand which chapters belong to which part of Science. CBSE Class 10 Biology consists of 6 chapters. They are: Life Processes, Control and Coordination, How do Organisms Reproduce, Heredity and Evolution, Environment and Management of Natural Resources.
In the following passages, you can find what the above chapters include. You can begin with the chapter which you tend to find more interesting and captivating.
Life Processes
The chapter includes all the life processes that are carried out by human beings, animals and plants. Students will acquire knowledge of different types of nutrition. They will learn about Photosynthesis in detail. Nutrition in humans has also been explained in this chapter. It elaborates on the functions of each organ in the human body that is responsible for nutrition. The chapter consists of an elaborate description of respiration in Plants and Animals, and transporation in Plants and Animals.
Control and Coordination
Since the control and coordination of our muscles are controlled by the Nervous System, students will find a comprehensive explanation of The Nervous System, the various types of movements that a plant makes along with a description of The Endocrine System and different types of glands present in the human body.
How do Organisms Reproduce
The fundamental concept of this chapter is reproduction. In this chapter, students will learn about the various ways through which plants reproduce. Both sexually and asexually. The chapter includes intricate information about asexual and sexual reproduction that is carried out by plants. It also explains the Human Reproductive System comprehensively. Each organ that is involved in the process of reproduction has been highlighted with a description of it along with its functions. The chapter states the ways in which one can maintain and take care of their reproductive health and talks about the various contraceptive methods.
Heredity and Evolution
Heredity and Evolution is one of those chapters in CBSE Class 10 Science that answers a lot of doubtful questions that students have. If students read this chapter carefully they will be able to understand Heredity, Inheritance, and Speciation. They will not only learn about the various ways in which human genes can mutate but also get an idea of how biologists carried out experiments to produce mutation in plants which have proved to be beneficial for the utilisation of the human race. It also states about the formation of fossils and human evolution. It talks about Charles Darwin’s famous ‘Theory of Evolution’ and his contribution towards the evolution of human beings.
Environment
The chapter on the Environment deals with the various types of modes of nutrition that plants and animals dwell on. The different components of the environment, that is Abiotic and Biotic Components. This chapter will let students have an understanding of the ecosystem, the trophic levels, the food chain, and the flow of energy. It also emphasizes the law of conservation of energy.
Management and Natural Resources
Management and Natural Resources can be considered as a chapter in which one can understand the importance of nature from a biological perspective. It states about the pollution in the Ganga river, the importance of managing our natural resources, and ways through which one can conserve these resources. This chapter is an eye-opener for the young generation to make them aware of the various problems that our environment is facing and to take action according to the ways that have been highlighted in this chapter.
Conclusion
Therefore, as students learn the importance of these chapters they will be aware of their bodies, will take care of their bodies and the environment. They will end the session with a lot of knowledge about the functioning of life and the environment.
