Question

Regeneration of Hydra is

• A. Morphollaxis by interstitial cells
• B. Epimorphosis by interstitial cells
• C. Epimorphosis by archaeocytes
• D. Epimorphosis by glandular cells

Answer 1

The correct option is A Morphollaxis by interstitial cells

The reconstruction of an entire animal from a small fragment by reorganizing the existing cells is called Morphallaxis. The regenerated animal is far smaller than the original one after the completion of the process. It grows to attain the normal size. In Hydra, morphallaxis takes place by intestinal cells.

So, the correct option is ‘Morphollaxis by intestinal cells’.
