xylem in dorsiventral leaves is directed towards

Options

A. upper epidermis
B. lower eqidermis
C. surrounds phloem
D. surrounded by phloem

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of Dorsiventral Leaves**:
- Dorsiventral leaves, also known as bilateral leaves, have two distinct surfaces: the upper (adaxial) surface and the lower (abaxial) surface. The upper surface is typically exposed to sunlight, while the lower surface is shaded.

2. **Identifying the Location of Xylem**:
- In dorsiventral leaves, the xylem is primarily located on the adaxial side, which is the upper side of the leaf. This positioning allows for efficient transport of water and nutrients from the stem to the leaf.

3. **Role of Xylem**:
- The xylem is a type of vascular tissue responsible for the conduction of water and dissolved minerals from the roots to the rest of the plant. It also provides structural support, allowing plants to grow larger.

4. **Analyzing the Options**:
- Given the options:
- A) Upper epidermis
- B) Lower epidermis
- C) Surrounds phloem
- D) Surrounded bifloem
- The correct answer is option A, as the xylem is directed towards the upper epidermis in dorsiventral leaves.

5. **Conclusion**:
- Therefore, the xylem in dorsiventral leaves is directed towards the upper epidermis.
