Question

Which is 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 piece of Planaria into many new individuals

Answer 1

The correct option is A Morphallaxis - Regeneration of two transversely cut equal pieces of one Hydra into two small Hydra

Regeneration is of two types: Morphallaxis and Epimorphosis.

In Morphallaxis, any cut part of the organism regenerates into whole organism. For example, Planaria and Hydra can regenerate into whole organisms from a cut part.

In Epimorphosis, the cut or injured part of the organism is repaired. For example, Lizard repairs it's cut tail.

So, the correct answer is 'Morphallaxis - Regeneration of two transversely cut equal pieces of one Hydra into two small Hydra'.
