Answer 1

Regeneration

Some animals like Hydra and Planaria can regenerate into a complete individual from a single segment of their body part.

Thus, regeneration is a type of asexual reproduction in which the development of a new organism occurs from just a broken or cut part of parent organism.

This is carried out by specialised cells which proliferate and make a large number of cells. From this mass of cells, different cells now undergo changes to become various cell types and tissues to make a full organism.

The regeneration of an organism from its cut body parts occurs by the process of growth and development. The cells of cut part divide and form mass of cells. These formed newly cells then change their shapes or become specialised to form different types of tissues and organs.

Answer 2

No, it can be the way of reproducing except in an organism called spirogyra, which grow with help of the process of fragmentation.
