Plants adapted to deserts have

Options

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

Answer

To solve the question "Plants adapted to deserts have", we need to analyze the options provided and understand the adaptations of desert plants, also known as xerophytes.

### Step-by-Step Solution:

1. **Understanding Xerophytes**:
- Xerophytes are plants that have adapted to survive in environments with very little water, such as deserts. Their adaptations help them minimize water loss and maximize water absorption.

2. **Analyzing the Options**:
- **Option 1: Sunken Stomata**:
- In desert plants, stomata (tiny openings for gas exchange) are often sunken or located in deep pits. This adaptation helps reduce water loss by minimizing exposure to air and reducing transpiration.

- **Option 2: Deep Roots**:
- Desert plants typically have deep root systems that allow them to access water from deeper soil layers. This adaptation is crucial for survival during dry periods when surface water is scarce.

- **Option 3: Thick Cuticle**:
- A thick cuticle is a waxy layer on the surface of leaves and stems that helps to prevent water loss. This adaptation is essential for reducing transpiration in arid environments.

- **Option 4: All of the Above**:
- Since all the adaptations mentioned in options 1, 2, and 3 are characteristic of desert plants, this option suggests that all the adaptations are present.

3. **Conclusion**:
- Since all three adaptations (sunken stomata, deep roots, and thick cuticle) are features of plants adapted to desert conditions, the correct answer is **Option 4: All of the Above**.

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