The third chapter of the Lakhmir Singh Class 10th Biology is 'How Do Organisms Reproduce?'. The chapter deals with the fundamentals of reproduction in animals and plants. Along with reproduction, it also gives the students a composing idea about genetics. The structured question format of the chapter makes it easy for the students to understand the various topics. The chapter is quite long, but as this chapter covers all the confusions in the form of questions, it is very feasible for the students to understand it through answers rather than just going through all the topics. Thus, the chapter runs deeper and highlights the importance of reproduction in our lives. The chapter covers topics like:
The chapter explains reproduction into two main categories- sexual and asexual. Sexual reproduction is where the cells from two parents meet to form the next generation. Asexual reproduction occurs from a single parent, and the next generation comes via budding, fragmentation, spore formation, binary and multiple fission, and regeneration. These processes are seen in microorganisms. The methods of vegetative propagation and artificial propagation are applied to plants. The chapter further explains sexual reproduction, where the male and the female organs are explained in detail, and their functions are discussed. The chapter also explains the diseases that are transmitted sexually and what steps can be taken to prevent those. The chapter's approach is detailed as it contains a hundred questions and makes it easy for understanding. The various kinds of questions like short, very short, long, fill in the blanks, and multiple-choice questions are given. The answers are explanatory and include diagrams wherever necessary. The concept of Hereditary begins from this chapter as it becomes easy to explain those concepts if a student has understood reproduction. The formatting of this chapter makes it very interesting and ensures students do not get bored while learning.
