In xerophytic leaf the stomate are situated

Options

A. On both surfaces
B. On upper surface
C. On lower surface
D. Absent from both surfaces

Answer

**Step-by-Step Solution:**

1. **Understanding Xerophytes:**
- Xerophytes are plants adapted to survive in dry environments, such as deserts. They have special features to minimize water loss.

2. **Role of Stomata:**
- Stomata are small openings on the leaf surface that allow for gas exchange (CO2 in, O2 out) and transpiration (water vapor loss).

3. **Transpiration in Xerophytes:**
- In xerophytic plants, the rate of transpiration is typically high due to high temperatures and low humidity in their environments.

4. **Adaptations to Minimize Water Loss:**
- To reduce water loss, xerophytes have evolved adaptations such as sunken stomata. This means that the stomata are located deeper within the leaf surface rather than being exposed directly to the air.

5. **Location of Stomata in Xerophytic Leaves:**
- In xerophytic leaves, stomata are primarily found on the lower surface of the leaf. This positioning helps to minimize exposure to wind and direct sunlight, thereby reducing transpiration.

6. **Conclusion:**
- Therefore, the correct answer to the question is that in xerophytic leaves, the stomata are situated on the lower surface.

**Final Answer:**
- The stomata in xerophytic leaves are situated on the **lower surface** (Option C).
