Question

Vegetative propagation by leaves is found in
(A) Albizzia lebbek
(B) Dalbergia sisso
(C) Bryophyllum diagremontianum
(D) Murraya sp

Answer 1

Hint: Reproduction is a biological process in which an organism gives rise to a new offspring. It is of two types: sexual and asexual. While in animals and other simpler organisms the term asexual is used but in plants, vegetative propagation is used. Vegetative propagation is the reproduction in which new plants arise from the parts of the plants. The units of vegetative propagation are runner, sucker, rhizome, tuber, offset, bulb.

Complete answer:
(A) Albizzia lebbek:
Albizia lebbek is a species of Albizia which is found in tropical and subtropical regions. Worldwide it is known as siris. It is used in environmental management, forage, medicine and wood. They have ordinary roots which develop adventitious buds which grow to new plants.

(B) Dalbergia sisso:
Dalbergia sisso is also known as Indian rosewood. It is fast-growing hardy deciduous rosewood. They have whitish or pink colour flowers. Found in Indian sub-continent. They also propagate through the root.

(C) Bryophyllum diagremontianum:
It produces plantlets along the margins of its leaves. When the leaves mature enough, they drop off on the ground and form small roots in any suitable soil beneath. Then new plants arise from those leaves after coming in contact with the soil.

(D) Murraya sp:
Murray asp is flowering plants in the citrus family. Found in Asia, Australia and the pacific islands. They are used in traditional medicine which can treat fever, pain and dysentery. The vegetative propagation is through the root.

Hence, the correct answer is option (C).

Note: In above we detailed the vegetative propagation in different plants which form a new plant. There are different types of vegetative propagules which help in the formation of new organisms. This term is only used in plants.
