Question

What is regeneration can it be considered as mode of reproduction

Answer 1

Regeneration is a type of asexual reproduction by which an organism is capable of regrowing certain body parts.

Answer 2

In biology, regeneration is the process of renewal, restoration, and growth that makes genomes, cells, organisms, and ecosystemsresilient to natural fluctuations or events that cause disturbance or damage.[1] Every species is capable of regeneration, from bacteria to humans.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5]where after the necrotic tissue comes fibrosis.[5] At its most elementary level, regeneration is mediated by the molecular processes of gene regulation.[6][7]Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traitsallowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes.[8] Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method of budding.

The hydra and the planarian flatworm have long served as model organisms for their highly adaptive regenerative capabilities.[9]Once wounded, their cells become activated and start to remodel tissues and organs back to the pre-existing state.[10] The Caudata("urodeles"; salamanders and newts), an orderof tailed amphibians, is possibly the most adept vertebrate group at regeneration, given their capability of regenerating limbs, tails, jaws, eyes and a variety of internal structures.[2] The regeneration of organs is a common and widespread adaptive capability among metazoan creatures.
