Question

illustrate the following with the help of suitable diagrams .
a) Regeneration in planaria
b) budding in hydra​

Answer 1

(A) In the case of regeneration, the organism has the ability to develop the body part which has been lost due to an accident. Many sea stars reproduce asexually by regeneration. For example, if the arm of an individual sea star is broken off it will regenerate a new sea star.

(B) Budding:

Budding is a form of asexual reproduction. There is a formation of an outgrowth from the body which develops into a new individual. The buds grow and develop by remaining attached to the body of the parent. When the bud develops to a particular size, the bud gets detached and grow individually. In Hydra, a bud forms that develops into an adult, which breaks away from the main body.
