Leaves of Nelumbo plant are

Options

A. Epistomatic
B. Hypostomatic
C. Amphistomatic
D. None of the above.

Answer

### Step-by-Step Solution:

1. **Identify the Plant**: The question refers to the leaves of the Nelumbo plant, which is commonly known as the lotus.

2. **Understand the Habitat**: The lotus is an aquatic plant, meaning it grows in water. This characteristic influences the structure of its leaves.

3. **Examine Leaf Structure**: The leaves of the lotus are large and float on the surface of the water. This floating nature is crucial for their function and adaptation to the aquatic environment.

4. **Stomata Location**: In lotus leaves, the stomata (tiny openings for gas exchange) are located only on the upper surface of the leaves. This is an important feature that differentiates them from other types of leaves.

5. **Define Leaf Types**:
- **Epistomatic**: Leaves with stomata only on the upper surface (like the lotus).
- **Hypostomatic**: Leaves with stomata only on the lower surface (e.g., apple and mulberry).
- **Amphisomatic**: Leaves with stomata on both surfaces (e.g., potato, tomato, and brinjal).

6. **Conclusion**: Since the lotus leaves have stomata only on the upper surface, they are classified as **epistomatic** leaves.

### Final Answer:
The leaves of the Nelumbo plant are **epistomatic**.
