(a) Budding, fragmentation and regeneration, all are considered as an asexual mode of reproduction. Why?
(b) With the help of neat diagrams, explain the process of regeneration in Planaria.
(a) Fragmentation, regeneration and budding are considered as an asexual type of reproduction because all of them involve only one parent and produce a new organism through mitotic division. In these methods, gametes are not involved in reproduction.
(b) Planaria can be cut into any number of pieces and each piece grows through specialized cells into complete/developed organisms.
