Question

The vegetative reproduction in Bryophyllum takes place through which organ?
A) Root
B) Stem
C) Leaf
D) Seed

Answer 1

Vegetative propagation can be defined as an asexual mode of reproduction which happens via root, leaves and stem.

Complete answer:
Let us first know more about vegetative reproduction before we find the correct answer. Vegetaitive propagation is a mode of asexual reproduction in plants which can occur via fragmentation and regeneration of specific parts.

Option A and B: In bryophyllum the vegetative reproduction is not seen via the root and the stem as they have epiphyllous buds which grow on the leaves. Therefore, this is the incorrect option.
Option C: In Bryophyllum, the vegetative reproduction happens via the leaves. Therefore, this is the correct option.
In Bryophyllum, on the leaf notches adventitious buds are formed, and they grow until they are big enough to survive on their own. Once, they are big enough, they detach themselves and grow on soil and give rise to the future plant. These buds are known as epiphyllous buds.
Option D: Seed is a natural mode of reproduction and not vegetative mode of reproduction. Therefore, this is the incorrect option.

Thus, the correct option is (C) Leaf.

Note: The natural ways of vegetative propagation are,

Bulbs - They have an underground stem to which leaves are attached and they have the ability to store. >leaves. Apical bud is present in the centre of the bulb and it is where shoots are developed from.
Roots - New plants are produced from modified roots which are known as tubers.
Stem - New plants arise from modified stems which are known as runners.
