Chapter 8 How do Organisms Reproduce: Reproduction is a biological process by which new individual organisms are born from their parents. It involves creating a new DNA copy and other cellular apparatus. Reproduction is not an essential process for sustaining the life of an individual. Each individual organism exists because of reproduction. It is a fundamental feature of all known life.

In this chapter, you will study reproduction, how it takes place, why it is necessary for the living organisms, and what are the different modes of reproduction in single organisms, sexual reproduction in flowering plants, sexual reproduction in human beings. Terms like fission, fragmentation, regeneration, budding, vegetative propagation and spore formation are also explained with examples.
