Regeneration???? Define it

Dear student, Regeneration is a mode of asexual reproduction and is mainly associated with the animals. Regeneration is of two types, in the first type, a part of the body that gets broken off or cut is regenerated. For example, lizards cast off their tails to escape predators and then regenerate them. The other type of regeneration involve the capacity to give rise to an entire organism from a cut part. It is seen in small invertebrates such as planaria and Hydra. Thanks and Regards
