Sunken stomata are usually found in

Options

A. `C_3` plant
B. CAM plant
C. `C_4` plant
D. Insectivorous plant

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where sunken stomata are usually found. Stomata are tiny openings on the surface of leaves that allow for gas exchange.

2. **Identifying the Type of Plants**: Sunken stomata are primarily found in xerophytic plants. Xerophytes are plants adapted to survive in environments with very little water, such as deserts.

3. **Function of Sunken Stomata**: The main purpose of sunken stomata is to minimize water loss. By being sunken, these stomata reduce air movement around them, which helps to conserve moisture within the plant.

4. **Behavior of Stomata in Xerophytic Plants**: In xerophytic plants, stomata often open at night and close during the day. This adaptation helps to reduce water loss during the hotter parts of the day when evaporation rates are higher.

5. **Examples of Xerophytic Plants**: Common examples of xerophytic plants include cacti and succulents, which exhibit these adaptations to thrive in arid conditions.

6. **Conclusion**: Therefore, the correct answer to the question is that sunken stomata are usually found in xerophytic plants.

**Final Answer**: Sunken stomata are usually found in xerophytic plants.
