Plants adapted to deserts have

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Environment**: Desert plants are adapted to survive in arid conditions where water is scarce. The adaptations they possess are crucial for their survival.

2. **Sunken Stomata**: One of the key adaptations is the presence of sunken stomata. Stomata are small openings on the leaves that allow for gas exchange. In desert plants, these stomata are often sunken to minimize water loss through transpiration. This adaptation helps retain moisture within the plant.

3. **Thick Cuticle**: Desert plants also have a thick, waxy cuticle on their leaves and stems. This cuticle acts as a barrier to water loss, preventing evaporation. The thickness of the cuticle is essential in reducing the amount of water that escapes from the plant.

4. **Deep Roots**: Another important adaptation is the development of deep root systems. These roots allow the plant to access water that is deeper in the soil, which is crucial for survival in a desert environment where surface water is often unavailable.

5. **Conclusion**: Given these adaptations—sunken stomata, thick cuticle, and deep roots—it is clear that desert plants possess all of these features to survive in their harsh environment. Therefore, the correct answer to the question is "all of the above."

**Final Answer**: Plants adapted to deserts have sunken stomata, deep roots, thick cuticle, all of the above.
