REPRODUCTION IN ORGANISMS:VEGETATIVE PROPAGATION: In plants the units of vegetative propagation such as runner, rhizome, sucker, tuber, offset and bulb are giving rise to new offspring. These s¬tructures are called vegetative propagules. Formation of these structures does not involve two parents. The process involved is asexual.Are you aware how plants like potato, sugarcane, banana, ginger, and dahlia are cultivated? Determine the site of origin of the new plantlets in the plants shown. You will notice that they invariably arise from the nodes present in the modified stems of these plants.Onion is stem modification. Adventitious roots are grown from discoid in the soil. Adventitious buds arise from the notches present at margins of leaves of Bryophyllum. This ability is fully exploited by gardeners and farmers for commercial propagation of such plants.Terror of Bengal' aquatic plant Water Hyacinth drains oxygen from the water, which leads to death of fishes. Introduced in India for its beautiful flowers and shape of leaves propagate at phenomenal rate spread all over water body within a short period of time. It is very difficult to get rid of them.Now let us see few examples of vegetative propagules in Angiosperms. 1 Eyes of Potato 2 Rhizome of Ginger 3 Bulbils of Agave. 4 Leaf buds of Bryophyllum 5 Offset of Water Hyacinth.Rhizome - Modified stem grows horizontally. Distinct nodes and internodes are present with marked apical and auxiliary buds. Adventitious roots present at the ventral side.Ex: Ginger Gingiber, Turmeric and Curcuma.Tuber: In Solanum tuberosum half moon like structures called eyes of potato. These eyes indicates the position of nodes and internodes. Scale leaves and auxillary buds present, apical bud is also present.Tubers have no roots. Ex. Solanum tuberosum Potato, Heliander tuberosus. Onion: underground steam modification, adventitious roots grow towards the soil. Fleshy scaly leaves which are eaten grow above soil -- aerial. Auxiliary buds produce new plant, apical bud shows inflorescence.Tunicate bulbs are seen in Allium sepa Onion. The imbricate bulbs are seen in Allium sativum Garlic. Corm: Underground steam modification, grows vertically in the soil. Nodes and internodes present. Scale leaves arising at node. Apical and auxiliary buds are present. Auxiliary roots produce daughter roots. Corm shows contractile roots which are helpful to put the corm in distinct depth. Ex: Amorphophallus, Colocasia, Diascorea etc.

[@chseshamma7185]

may I know what is the exact definition for vegetative propagation with it's types please

[@BiologicalYTLessonwithSM]

Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or a specialized reproductive structure.

[@avaerguero1576]

Vegetative propagation is a type of asexual reproduction that produces progeny by any vegetative propagule (rhizome, tubers, suckers etc.) without gamete formation and fertilization of male and female gametes. For example, Tuber of potato, the rhizome of ginger.
