Question

Which is the correct example of the type of regeneration out of two major types?
A)Morphallaxis- Regeneration of two transversely cut equal pieces of one Hydra into two small Hydra.
B)Epimorphosis- Replacement of old and dead erythrocytes by the new bonos.
C)Morphallaxis- Healing of wound in skin.
D)Epimorphosis- Regeneration of crushed and filtered out pieces of Planaria into many new individuals.

Answer 1

Hint: The natural phenomenon of replacing or repairing, in plants and animals, damaged or missing cells, organs, tissues or whole parts of the body to full function.

Complete answer:
Regeneration research for its future application in medicine, such as the treatment of a number of injuries and diseases, is being performed.

Morphallaxis and Epimorphosis are two forms of regeneration.
In Morphallaxis, every cut section of the organism regenerates into the whole organism. Planaria and Hydra, for example, can regenerate into whole organisms from a split section..
The cut or wounded part of the body is healed in Epimorphosis. Its split tail, for starters, Lizard fixes.

Thus, the right answer is 'Morphallaxis - Reproduction of two identical parts of one Hydra transversely split into two small Hydra'.

Hence, the correct answer is option (A)

Note: The noteworthy characteristic of Morphallaxis is that the vast majority of regenerated tissues originate in the orgasm from tissue that is already present. I.e. the hydras one severed segment shapes into a smaller version of the original hydra, around the same size as the segment being severed. There is, therefore, a tissue ‘exchange’ occurs.
