Question

Explain the process of regeneration in Planaria. How is this process different from reproduction?

Answer 1

Regeneration in Planaria :
Planaria have the ability to give rise to new individuals from their body parts. This process is called regeneration. If the body of Planaria is somehow cut or broken up into many pieces, each piece grows into a complete organism. Regeneration differs from reproduction in the sense that, regeneration can take place from any part of the organism, example cut tail of a lizard. However, reproduction is a process in which new organism is formed through specialized cells called gametes. Also, regeneration does not necessarily give rise to a new individual, whereas reproduction always produces new individuals from the parent organism.
