Question

What is regeneration ? Explain with the help of a diagram how this process is carried out in Planaria.

Answer 1

Explanation:

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

In biology, regeneration is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans.
