Xerophytes possess

Options

A. Sunken stomata
B. Deep roots
C. Thick cuticle
D. All the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Xerophytes**: Xerophytes are plants that have adapted to survive in environments with very low water availability, such as deserts. They have developed several adaptations to minimize water loss and maximize water retention.

2. **Identifying Adaptations**:
- **Thick Cuticle**: Xerophytes possess a thick and waxy cuticle on their leaves. This cuticle helps reduce water loss through evaporation by providing a barrier against the external environment.
- **Sunken Stomata**: They have stomata that are often sunken into the leaf surface. This adaptation reduces the exposure of the stomata to air, thereby minimizing transpiration (loss of water vapor).
- **Deep Roots**: Xerophytes typically have deep and extensive root systems. These roots allow the plants to access water from deeper soil layers and help them survive prolonged dry periods.

3. **Conclusion**: Since all these adaptations (thick cuticle, sunken stomata, and deep roots) are characteristic features of xerophytes, the correct answer to the question "Xerophytes possess" is **"all of the above."**

4. **Final Answer**: Therefore, the correct option is **D) all of the above**.
