The two modes of asexual reproduction in animals are:

(i) Binary fission, (ii) Budding.

Vegetative propagation is a form of asexual reproduction. It is the ability of plants to produce new plants from the vegetative parts, such as leaves, stems and roots, under favourable conditions.

Advantages of vegetative propagation :

(i) Only one parent is required for reproduction; this eliminates the need of special mechanisms (pollination).

(ii) Many plants are able to tide over unfavourable conditions because of the presence of vegetative reproductive parts like tubers, corns and bulbs.

(iii) Plants that do not produce seeds are propagated by this method, e,g., sugarcane and potato.

(iv) Vegetative propagation is a cheaper, easier and rapid method of propagation in plants than growing plants from their seeds. For example, lilies grow very slowly and take four to seven years to develop flowers when their seeds are grown, but flowers are produced only after a year or two when grown vegetatively.

(v) The trait (character) of the parent plant is preserved and the offspring are genetically identical.
