Question

Repairment of a damaged tissue by cell division is

• A. Epimorphosis regeneration
• B. Morphallaxis regeneration
• C. Exponential growth
• D. Deaccelerating growth

Answer 1

The correct option is A Epimorphosis regeneration

Epimorphosis type of regeneration involves dedifferentiation of adult forms, so as to form an undifferentiated mass of cells. For example, limb regeneration in amphibians.
Morphallaxis is the type of regeneration, which mainly occurs by remodelling of existing tissues thus involving very little new growth. It subsequently increases in size and becomes normal after feeding.
Thus, the correct answer is option (A), 'Epimorphosis regeneration'.
