Reproduction in Organisms – It’s Meaning and Importance

The study of cellular Biology Topics is essential to understanding the workings of all living organisms.

Explain the Importance of Reproduction in Organisms

Reproduction is an essentially biological process where the offspring grows, matures, and then produces new offspring through a series of cyclical events of birth, growth, senescence, and death in the whole life span. It is a process by which an organism produces young ones of its kind. In a general sense reproduction is one of the most essential concepts in biology. It means making a copy, a likeness and thereby providing for the continued existence of species. It is one of the fundamental characteristics of living organisms.

Genetic variation is created and inherited during reproduction. Among living organisms, reproduction is one of the vital and fundamental characteristic features responsible for their survival and perpetuation. It regulates the proper transmission of genetic material from one generation to the second generation and the next. It ensures that the species survives and maintains its existence over a long period.

At its lowest level, therefore, reproduction is chemical replication. As evolution progressed, cells of successively higher levels of complexity must have arisen and they needed to have the ability to make likenesses of themselves.

Although reproduction is often considered solely in terms of the production of offspring in animals and plants, the more general meaning has far greater significance to living organisms. To appreciate this fact, the origin of life and The evolution of organisms must be considered. One of the first characteristics of life that emerged in primeval times must have been the ability of some primitive chemical system to make copies of itself.

Biogenesis: It is the production of new living organ¬isms or organelles. The law of biogenesis, attributed to “Louis Pasteur”, is the observation that living things come only from other living things, by reproduction (e.g., a spider lays eggs, which develop into spiders). That is, life does not arise from non-living material, which was the position held by spontaneous generation.

Definition of Reproduction: The process by which a fully developed organism produces a new individual of its kind, is known as reproduction.

Importance of Reproduction

1. Maintaining the Existence of Life:
The living world maintains its existence by producing new descendants through reproduction.

2. Multiplication:
Organisms multiply their species by reproduction.

3. Maintaining Continuity:
Through reproduction, living organisms maintain their succession in nature.

4. Setting up the Balance in Nature:
Production of similar offspring helps to maintain the balance on this earth.

5. Helps in Evolution:
The variations appearing through sexual reproduction helps in evolution.

6. Origin of Mutation:
There is a chance for mutation at the time of sexual reproduction by which new species may originate.

7. Production of Hybrid Varieties:
Hybrid varieties may be produced by inter-specific sexual reproduction which can adjust easily to the changed environment.

8. Produce genetic diversity:
Reproduction introduces variations in the organisms. Useful variations are essential for adaptations and evolution. Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. Asexual reproduction, on the other hand, does not need sperm and eggs since one organism splits into two organisms with the same combination of genes.

9. Species continuity:
The continuity of species is maintained by reproduction.

10. Organization of population:
Reproduction maintains the population of young, adult, and aged persons.
