define reproduction and it's significance
Answers
Definition:- The process by which an organism reproduces young ones of it's own kind is known as reproduction.
Significance:- It leads to an increase in the number of individuals of a species and maintains the continuity of life.
☞Reproduction is the biological process by which new individual organisms – "offspring" – are produced from their "parents". Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual.
The main significance of reproduction is to maintain continuity of species. It also helps in studying evolution as sexual reproduction results in variation among the species.
Explanation:
➜Reproduction is the biological process by which existing organisms give rise to their offspring. Every existing plant, animal or other living organism is the result of biological reproduction. Reproduction maintains the thread of life.
➜Reproduction can be of two types – Asexual mode and Sexual mode.
➜Reproduction is carried out by different living organisms to perpetuate their species. Reproduction is an integral feature of all living beings.
➜Reproduction is important for the survival of all living things. Without a mechanism for Reproduction, life would come to an end.
➜Reproduction helps in maintaining a proper balance among various biotic constituents of the ecosystem. Moreover, reproduction also facilitates evolution because variations come through reproduction; over several generations.
➜Reproduction can be of two types – Sexual mode and Asexual mode.
☞Asexual Reproduction:
When a single parent is involved and no gamete formation takes place; the method is called asexual reproduction. No meiosis happens during asexual reproduction.
☞Sexual Reproduction:
When two parents are involved and gamete formation takes; the method is called sexual reproduction. Meiosis happens during gamete formation; which is an important step of sexual reproduction.
☞Significance of reproduction:
•Reproduction prevents all kinds of organisms from becoming extinct.
•Reproduction is not necessary for carrying out life processes of an individual but helps in increasing the individuals in a population.
•Reproduction is essential in creating variations in species through genetic recombination.
•Reproduction is necessary in the process of evolution by carrying favourable variations from one generation to another generation.
