Question 6

Define asexual reproduction. Describe two methods of asexual reproduction in animals.

Answer

Asexual reproduction may be defined as the reproduction in which only one parent is involved. The produced offspring is an exact copy of their parent or we can say identical to their parent.

Two methods of asexual reproduction in animals:

  1. Binary fission: It is type of asexual reproduction in which a single cell divides into two halves. For example: Amoeba, bacteria etc.

In Amoeba, one nuclei is divided into two nuclei then the division of body occur in two halves. Each half of the amoeba gets a nuclei and produces new organism by each half.

          binary fission

          2. Budding: This is a type of asexual reproduction in which bulges arises from the parent body. For example: Hydra. The bulges are known as bud.

In Hydra, cells divide rapidly and some buds arise from specific site. These buds arise into a small individual when attached to the parent plant. When these becomes mature, they get detached from the parent body and become an independent individual.
