Reproduction And Its Importance

It is a biological process in which an organism gives rise to young ones or offsprings similar to itself.

There is a continuous cycle of birth, growth and death enabling the continuity of species, generation after generation.

Reproduction performs following functions :-

Based on the participation of one organism/parent or two, reproduction can be categorised into two types :-

  • Sexual reproduction : The offspring is produced by two parents (opposite sex) involving fusion of male and female gametes.
