During regeneration, modification of an organ to other organ is known as

  1. morphogenesis
  2. epimorphosis
  3. morphallaxis
  4. accretionary growth

Answer

(2) epimorphosis

Solution

Epimorphosis is regeneration in which the lost part is replaced by the formation of a blastema at the cut surface, whose cells proliferate and differentiate into a new structure.

In such epimorphic regeneration the new structure formed may be an organ different from the one that was lost (e.g. an antenna-like organ formed in place of an eye in crustaceans — heteromorphosis), i.e. one organ is modified into another.

∴ The process is epimorphosis.
