Question

During regeneration, differentiation of an organ to another organ occurs in:

• A. Morphogenesis
• B. Epimorphosis
• C. Morphollaxis
• D. Phyllotaxy

Answer 1

The correct option is B Epimorphosis

Epimorphosis and morphallaxis are types of regeneration. Epimorphosis is the process in which existing tissues and organs dedifferentiate into a cell mass, which re-differentiates to form another tissue or organ. This process is seen during regeneration in lizards.

Morphallaxis is also a process of regeneration of a lost tissue. But it does not involve de-differentiation and re-differentiation. The existing cells reorganize to form the lost tissues. This type of regeneration is obsedrved in hydra.

Morphogenesis is the development of the morphology or the shape and pattern of an organism.

Phyllotaxy is the arrangement of leaves on the stem/axis.
