2.Describe the different methods of asexual reproduction. Give example

Answer»

The various modes of asexual reproduction in plants are as follows:(i)Vegetative propagation:It is the ability of a plant to produce new plants from roots,stems, leaves, and buds. Vegetative propagation is divided into two types.Natural vegetative propagation: This type of vegetative propagation occurs easily innature and involves simple vegetative parts. Potato plant sprouting from an eye is acommon example.

Artificial vegetative propagation: This type of vegetative propagation is performedmanually and generally occurs in laboratory conditions. The formation of a completeplant from a stem cutting of rose is a common example of this method.

(ii)Budding:It involves the formation of a new individual from a bulb-like projectioncalled a bud. The bud grows and gets detached from the parent to form a new individual.It is commonly observed in yeast.(iii)Fragmentation:It is a form of asexual reproduction where a new organism is formedfrom the fragments of the parent body. It is the only mode of asexual reproduction inSpirogyra.(iv)Spore formation:Many non-flowering plants reproduce through spore formation.Spores are tiny cells protected by a thick wall. Fungi such as bread moulds reproduceasexually using this method.
