Leaf helps in vegetative propagation in

Options

A. Arabidopsis
B. Bryophyllum
C. Sensevieria
D. Brassica

Answer

To solve the question "Leaf helps in vegetative propagation in," we need to analyze the options provided and identify which plant uses leaves for vegetative propagation.

### Step-by-Step Solution:

1. **Understanding Vegetative Propagation**:
- Vegetative propagation is a form of asexual reproduction where new plants grow from parts of the parent plant, such as leaves, stems, or roots.

2. **Analyzing the Options**:
- A. **Arabidopsis**: This plant is primarily known for its use in genetic studies and does not primarily propagate through leaves.
- B. **Bryophyllum**: This plant is well-known for its ability to propagate through its leaves. It has notches along the leaf margins where new plantlets can develop.
- C. **Senescenaria**: This plant does not typically propagate through leaves.
- D. **Brassica**: This is a genus that includes many vegetables, but they do not propagate through leaves.

3. **Identifying the Correct Answer**:
- Among the options, **Bryophyllum** is the only plant that uses its leaves for vegetative propagation effectively. The leaf notches can produce new plants when they fall to the ground.

4. **Conclusion**:
- Therefore, the correct answer is **B. Bryophyllum**.
