Answer 1

Answer: (B)

Vegetative propagation is a method of multiplication in which a somatic part of the plant detaches from the body of the mother and develops into a new independent plant under suitable environmental conditions. The detachable somatic part involved in vegetative propagation is called vegetative propagule. Vegetative reproduction can be studied under the following subheadings:
1. Stem
• Underground stem
• Subaerial stem
• Aerial stem
• Bulbils
2. Leaves
3. Root
Stems
• Underground stem: It is non-green, food storing, perennating structure present below the surface of the soil. It is of several types like tuber, rhizome (ginger), bulb (onion).
• Subaerial stem: It is a weak stem that takes the support of the ground for spreading. It is of three different types-offset, runner, sucker.
• Bulbils: These are large size fleshy buds that are specialized for vegetative reproduction. For this bulbil must fall from the plant and reach the soil. They can be present at variable positions on the plant. In Agave, bulbils are modified floral buds that develop on the floral axis. E.g., Agave (century plant), Oxalis, Ananas, Dioscorea, Lily, etc.
Leaves: Leaves of several plants having adventitious buds help in vegetative reproduction. In Bryophyllum adventitious buds arise from the notches present at margins of leaves. E.g., Adiantum (walking fern), Begonia, Kalanchoe.
