notes
Regeneration:-
Many fully differentiated organisms have the ability to give rise to new individual organisms from their body parts.
That is, if the individual is somehow cut or broken up into many pieces, many of these pieces grow into separate individuals. For example, simple animals like Hydra and Planaria can be cut into any number of pieces and each piece grows into a complete organism. This is known as regeneration.
