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 :-

(i) Maintains life on the Earth.

(ii) Enables continuity of the species.

(iii) Creates variations among populations.

Several factors, which determine how an organism reproduces are :-

(i) The organism's habitat.

(ii) Its internal physiology.

(iii) Environmental conditions.

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

  •  Asexual reproduction :-The offspring is produced by a single parent with or without the involvement of gamete formation.
  • Sexual reproduction : The offspring is produced by two parents (opposite sex) involving fusion of male and female gametes.
