Question

In which plant vegetative propagation by leaf takes place

• A. Potato
• B. Byrophyllum
• C. Tomato
• D. Mustard

Answer 1

The correct option is B

Byrophyllum

The correct option is B:

Explanation of the correct option:

1. Vegetative reproduction is an asexual reproduction method in which the multicellular structures of the parents are removed and grown into a new plant.
2. In Byrophyllum, asexual reproduction occurs mostly by vegetative leaf growth.
3. In the leaves of Bryophyllum, there are notches on the margins where the meristem is present. These are the locations where epiphyllous buds emerge, with the ability to create new plants with shoots, small leaves, and adventitious roots.
4. A new plant may grow from each bud if a leaf of this plant is detached and falls on damp soil.
5. When the leaves of the Bryophyllum plant fall off, buds form on the leaf's margin, and the conditions are favourable for the growth of buds on the fallen leaf, which grow to produce a new plant.

Explanation of the incorrect option:

Option A:

Stem is used for vegetative propagation in potatoes.

Option C:

To produce seeds, the tomato plant reproduces sexually, which means it requires both female and male organs.

Option D:

Mustard is propagated through seeds. Seeds can be sown directly into soil that has been amended with well-rotted manure and compost.

Final answer: Vegetative propagation by leaf takes place in Byrophyllum.
