Question

Mention the mode of reproduction used by

a) Amoeba

b) Planaria

Answer 1

a) Amoeba reproduce by means of binary fission. It is a kind of asexual reproduction in which parent cell divides into two identical daughter cells. The cell elongates and nucleus divides into two daughter nuclei. This is followed by the formation of a transverse wall in the centre of the parent cell which results in the division of parent cell into two daughter cells which then separate and live independently.

b) Planaria has high power of regeneration. It reproduces asexually in which it loses a part of its body (generally tail), and the lost body parts grow into new individual.
