Text Solution

Verified by Experts

Regeneration: The process of getting back full organism from its body part is called regeneration. For example simple animals like Hydra and Planaria show regeneration.
Planaria (Flatworm) is found in freshwater ponds. If the body of planaria somehow gets cut into number of pieces then each body piece can regenerate into complete planaria.

It occurs by the process of growth and development. The cells of cut body part divide rapidly to make ball of cells. The cells present in ball of cells move to their proper places and form various organs and body parts of an organisms.
