During regeneration, modification of an organ to another organ is known as : -
A
Morphallogenesis
B
Epimorphosis
C
Morphallaxis
D
Accretionary growth
Detailed Solution
Regeneration is of two main types:
Epimorphosis: replacement of a lost part by growth of new tissue from the cut surface (e.g. regrowth of the tail of a lizard, limbs of salamander).
Morphallaxis: regeneration by remodelling (reorganisation) of the existing tissues without much new growth, e.g. a small piece of Hydra or Planaria re-forming a whole animal.
As per the answer key, the modification of one organ into another during regeneration is called epimorphosis.
(This answer is doubtful: transformation of existing tissue into another organ is usually described as morphallaxis.)
So, as per the answer key, the answer is epimorphosis.
