Regeneration is the capability of an organism to regenerate its parts when they get destroyed.
Ex: in planaria if any of its part gets cut or injured this organism has the capacity of dividing cell in that area.
Ex: in cockroach if its head is detached it can stay alive till few days but it can’t regenerate its head because Regeneration is carried out by specialized cells which are not present in non-regenerating organisms.
