What is regeneration?state a reason through it.

Answer 1

hello frnd...*_*

Regeneration, in biology, the process by which some organisms replace or restore lost or amputated body parts.



Regeneration, as one aspect of the general process of growth, is a primary attribute of all living systems. Without it there could be no life, for the very maintenance of an organism depends upon the incessant turnover by which all tissues and organs constantly renew themselves. In some cases rather substantial quantities of tissues are replaced from time to time, as in the successive production of follicles in the ovary or the molting and replacement of hairs and feathers. More commonly, the turnover is expressed at the cellular level. In mammalian skin the epidermal cells produced in the basal layer may take several weeks to reach the outer surface and be sloughed off. In the lining of the intestines, the life span of an individual epithelial cell may be only a few days.

Hey mate here is ur Answer ✌️
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 down into many pieces, many pieces grow into separate individuals.
For example, simple animal like Hydra and Planaria can be cut into many pieces and each piece grows into a new individual This is known as regeneration..
