Ans. The process of getting back a full organism from its body part is called regeneration. The simple animals like hydra and planaria show regeneration.
Explanation. If the body of planaria gets cut into a number of pieces, then each body piece can regenerate into a complete planaria by growing all the missing parts. The regeneration of an organism from its cut body part occurs by the process of growth and development. The cells of cut body part divide rapidly to make a ball of cells. The cells then become specialized to form different types of tissues with again form various organs and body part.
