The three methods of vegetative or asexual reproduction are:
1. Budding: In this method of reproduction, the body of the parent produces an offspring from a small bulb like projection called bud that grows and separates from the parent cell and forms a new cell.
2. Fragmentation: In this method, the body of the parent is split into smaller fragments when water and other nutrients are available. These smaller fragments or pieces grow and develop into new organisms.
3. Spore formation: In this method, spores are the vegetative (asexual) reproductive organs. These spores are covered by a hard protective layer which breaks down under favourable conditions to produce a new individual.
Following are the advantages of vegetative reproduction:
1. Reproduction takes places at a rapid rate under favourable conditions. A large number of new individuals are formed in less time from a single cell.
2. Offsprings formed out of vegetative reproduction have better chances of survival as large number of new individuals are produced.
