Reproduction is defined as the biological process by which organisms give rise to their own kind. This process of reproducing one’s own kind ensures the continuance of the variety of organisms that inhabit the earth.
Reproduction is a characteristic feature of every living being and has its own role to play in the body just like the other biological processes such as respiration, circulation, nutrition and others.
A naturally occurring feature of all organisms is to grow up. Microbes, plants, animals all need to grow up to an extent when they are able to perpetuate their own species. Thus, the species lives on from one generation to the next. The biological process involved in the perpetuation of species is called reproduction.
Reproduction may be defined as the biological process by which organisms give rise to their own kind. Reproduction may occur in two ways:
Bacterial and protozoan offspring may be produced by single individuals. This is termed asexual reproduction. Certain animals and many plants reproduce asexually.
When two individuals are involved in reproduction, it is termed sexual reproduction. In sexual reproduction, male gamete fuses with female gamete to mark the beginning of a new individual. This is a more common mode of reproduction in plants and animals.
