Question

When animals have capacity to develop whole body from a small portion by forming differentiated tissues from the stem cells, the phenomenon is called as

• A. Regeneration
• B. Morphallaxis
• C. Epimorphosis
• D. Restoration

Answer 1

The correct option is C Epimorphosis

Regeneration can occur in two forms: morphallaxis and epimorphosis.

Morphallaxis is a process of tissue reorganization observed in many lower animals following severe injury, such as bisection of the animal. The result is a similar type of cells which differentiate into same tissues. Morphallaxis can help in regeneration of smaller organisms in which there is no tissue differentiation.

Epimorphosis is the form of regeneration in which the stem cells are involved and they can form the different types of tissues in the organism. Thus, the whole organism can be regenerated by stimulation of the stem cells.

Thus, the correct answer is option C.
