This chapter primarily propagates the fundamental knowledge of biological processes that leads to the continuity of a species. The chapter highlights the mode of reproduction in both prokaryotic and eukaryotic cells. In addition, this chapter gives complete information on types of reproduction and their development. Therefore, the students get to understand the process taking place in the various organisms thoroughly.
The chapter highlights the two-mode of reproduction in brief:
1. Asexual reproduction
2. Sexual reproduction
It further presents the comparative session of unicellular reproduction with multicellular and points out the differences in their specific reproduction procedures. Students will learn the changes that occur during reproduction, both externally or internally, with a slight mention of its factors. The chapter further delves deeper into the fertilisation process and its significance in the development of the next generation. This topic also provides vital information on lower organisms like amoeba or hydra reproduction by process fission or budding.
Students also learn the basic concepts of how cells divide. This presents a broader understanding of genetics and chromosomes in higher classes. The text further discusses the involvement of male and female reproductive organs with structure in brief. Finally, the lesson further highlights the male and female gametes to understand all the concepts that refer to a vital process for survival.
Students are also introduced to some hormone involvement responsible for developing sex organs and accompanying sexual behaviour. Finally, the chapter provides requisite information on how or where fertilisation occurs with the explanation of events that lead to the development of a baby from the zygote.
