Vegetative reproduction

Vegetative reproduction

Vegetative reproduction is a form of asexual reproduction in plants. It does not involve flowers, pollination and seed production. Instead, a new plant grows from a vegetative part, usually a stem, of the parent plant. However, plants which reproduce asexually almost always reproduce sexually as well, bearing flowers, fruits and seeds.
Vegetative reproduction from a stem usually involves the buds. Instead of producing a branch,
the bud grows into a complete plant which eventually becomes self-supporting.
Since no gametes are involved, the plants produced
asexually have identical genomes and the offspring
form what is known as a clone.
In some cases of vegetative reproduction, the
structures involved also become storage organs and
swell with stored food, e.g. potatoes.

The principal types of vegetative reproduction
structures are bulbs, corms, rhizomes and runners.
