Reproduction

In the previous chapter we see advance concepts of Plants and humans. In this chapter we will learn reproduction in all living organisms.

Reproduction

Reproduction can be defined as production or generation of new offspring that are genetically similar to their parents. Reproduction is the characteristics of living organisms. It is essential for continuity of life. Every living organism reproduces by different methods. The method of reproduction will vary from unicellular microorganism to complex human being.

Every living organism contains the genetic material. The genetic material transmits from one generation to next generation. The genetic material can be divided into two types such as DNA (Deoxyribose nucleic acid) and RNA (Ribonucleic acid).

All the living organisms contain the genetic material that is either DNA or RNA but both. The DNA or RNA (genetic material) present within the nucleus of the cell.

The DNA or RNA contains chromosomes. The number of chromosomes differs from organism to organism.

Importance of Reproduction:

  1. It is essential for continuity of life of living organisms.
  2. The variation can be produced from reproduction; it leads to generation of new characteristics.
  3. It is the fundamental powers for heredity.

Types of Reproduction:

  1. Asexual Reproduction: It can be defined as the process where there is no fusion of gametes and only single parent involved. There are various types of asexual reproduction such as budding, regeneration, fission, etc.
  2. Sexual Reproduction: The reproduction that takes place in plants, animals and humans. In the process, fusion of gametes and involvement of two parents are present.
