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. It is reported in Porifers, Coelenterates, flatworms, Nemarteans, and some ascidians.

So, the correct option is ‘Porifers, Coelenterates, flatworms, Nemarteans, and some ascidians’.

A. Morphallaxis - The reconstruction of an entire animal from a small fragment by reorganizing the existing cells, is called Morphallaxis.

B.Epimorphosis - The regeneration of tissues or organs through the dedifferentiation of existing, differentiated adult tissues

C.Epigenesis - The theory, now generally held, that an embryo develops progressively from an undifferentiated egg cell.

D. Auxetic growth – Growth takes place by the influence of auxins.

So, the correct option is ‘Auxetic growth’.

Formation of new cells or tissues in the body organs is called Regeneration. It is first discovered in hydra by Abraham Trembley.

So, the correct option is ‘Hydra’.
