Bryophyllum diagremontianum is characterised by the formation of

Options

A. Plantlets in leaf notches while attached to plant
B. Plantlets from marginal notches when the leaf falls on the ground
C. Buds in the marginal notches of leaves
D. Plantlets on the leaves in the region of injury.

Answer

**Step-by-Step Solution:**

1. **Understanding the Plant:**
- Bryophyllum diagremontianum is a succulent plant known for its unique method of vegetative reproduction.

2. **Identifying the Reproductive Method:**
- This plant reproduces vegetatively, meaning it can produce new plants from its existing structures without the need for seeds.

3. **Observing Leaf Structure:**
- The leaves of Bryophyllum have notches along their edges. These notches are crucial for the plant's reproductive process.

4. **Formation of Plantlets:**
- In Bryophyllum, plantlets form in these leaf notches while the leaf is still attached to the parent plant. This is a key characteristic of the species.

5. **Potential for Germination:**
- When the leaf eventually falls to the ground, the plantlets can root in the soil and grow into new plants. However, the initial formation occurs while the leaf is still attached.

6. **Conclusion:**
- Based on the information gathered, the correct answer to the question is that Bryophyllum diagremontianum is characterized by the formation of **plantlets in leaf notches while attached to the plant**.

**Final Answer:**
- Option A: Plantlets in leaf notches while attached to the plant.
