In dorsiventral leaf, xylem is on

Options

A. adaxial side
B. abaxial side
C. laterla side
D. mesarch

Answer

### Step-by-Step Solution:

1. **Understanding Dorsiventral Leaf**:
- A dorsiventral leaf, also known as a dicot leaf, has two distinct surfaces: the upper surface (adaxial) and the lower surface (abaxial).

2. **Identifying the Vascular Bundles**:
- In a dorsiventral leaf, the midrib contains vascular bundles, which are responsible for the transport of nutrients and water.

3. **Types of Vascular Tissue**:
- The vascular bundles consist of two types of tissues: xylem and phloem.
- Xylem is responsible for transporting water and minerals from the roots to other parts of the plant.
- Phloem transports food produced in the leaves to other parts of the plant.

4. **Location of Xylem in Dorsiventral Leaf**:
- In a dorsiventral leaf, the xylem is located on the upper epidermis, which is also referred to as the adaxial surface.
- Conversely, the phloem is located on the lower epidermis (abaxial surface).

5. **Conclusion**:
- Therefore, in a dorsiventral leaf, the xylem is present on the adaxial surface.

### Final Answer:
In a dorsiventral leaf, xylem is on the **adaxial surface**.
