Answer 1

$\mathbb{\green{\huge{ANSWER:}}}$

Regeneration is a mode of asexual reproduction in some organisms. The process of getting back a full organism from its body parts is called regeneration. The simple multicellular animals like hydra and planaria show regeneration. <br> Regeneration in hydra: <br> If the body of hydra gets cut into a number of pieces, then each body piece can regenerate into a complete hydra by growing all the missing parts. <br> The regeneration of an organism from its cut body part occurs by the process of growth and development. <br> The cells of cut body parts divide rapidly to make a ball of cells. <br> The cells then become specialised to form different types of tissues which again form various organs and body parts.
