Question

Describe with examples natural methods of vegetative reproduction in flowering plants?

Answer 1

Hint: Vegetative method of reproduction is the type of asexual reproduction. It is the process in which a new plant is formed from a part of the plant by asexual means. Asexual here refers to the reproduction not involving fusion of gametes.

Complete answer:
Vegetative method of reproduction is a type of asexual reproduction.
> A new plant is formed by the part of the plant without involving the fusion of gametes.
> The vegetative parts from which new plants are formed includes rhizome, suckers, buds, tubers, roots, bulbs, corns, stem, etc.
> The vegetative propagation is the process that occurs through natural and artificial means.
Natural methods of vegetative reproduction mainly include:
> By stem tubers example- onions, turmeric, potato etc.
> By root tubers: example- dahlia, tuberous roots of sweet potato, asparagus etc.
> By suckers: example- roses, raspberries, gooseberries, etc.
> By bulbs: example- garlic, onions, tulips, aloe.
> From reproductive organs: flower buds of agave plants having bulbils.
> By leaves: bryophyllum, lilium.
> By runners or stolons: example- stolon.
> These all are the natural methods of vegetative reproduction in which a new plant is generated from the fragment of the parent plant or by the help of specialized structure.

Note:
Natural vegetative propagation usually occurs when an axillary bud grows into a lateral shoot and develops its own roots called as adventitious roots.
For example, Mosses forms small clumps of tissue called gemmae that are dispersed by smearing raindrops to form new plants.
