The chapter explains reproduction in various organisms and explains some of the important organisms used in different modes of reproduction depending on their body design. Organisms such as hydra can regenerate if they are broken into pieces. It also explains the male and female reproductive systems, changes in the body of puberty, examples of asexual reproduction where new generations are created from a single individual. Reproduction involves the creation of a DNA copy and additional cellular apparatus by the cell involved in the process. Depending on their body design, various organisms use different modes of reproduction. Roots, stems and leaves of some plants develop into new plants through vegetative propagation. These are examples of asexual reproduction, where new generations are created from a single individual. Reproduction in flowering plants involves the transfer of pollen grains from the anther to the stigma, which is referred to as pollination. It is followed by fertilisation.
