Question

In bryophyllum, the buds that arise from the notches of margins of leaves are called.

• A. Apical bud
• B. Axillary buds
• C. Terminal buds
• D. Adventitious buds

Answer 1

The correct option is D

Adventitious buds

The correct option is D.

Explanation of the correct option:

Option D:

1. The adventitious buds are known as epiphyllous buds.
2. These vegetative buds develop from the notches of leaves.
3. When these buds fall on the ground they can develop and germinate into a new plant.
4. Bryophyllum is a group of plants that grow flat leaves that can produce bulbils (axillary bud) capable of germinating into new plants.

Explanation of the incorrect options:

Option A:

1. An apical bud is a bud with meristematic tissue with the ability to develop into specialized tissue composed of undifferentiated cells.
2. Apical bud increases the vertical height and helps in growing the shoot of the plant.
3. This is an incorrect option as the apical buds do not arise from the notches of the leaf margins.

Option B:

1. Axillary buds are present in the axil of the leaf.
2. They help in the growth of lateral shoots.
3. They help in developing branches.
4. These buds are not responsible from the margins of the leaf.
5. This is an incorrect option.

Option C:

1. The terminal bud is located at the end of the growing shoot.
2. This bud does not have the capability of differentiation and growth.
3. Hence, this is also an incorrect option.

Final answer: In bryophyllum, the buds that arise from the notches of margins of leaves are called adventitious buds.
