Penumatophores possess

Options

A. Stomata
B. Water pores
C. Lenticels
D. Root hairs.

Answer

### Step-by-Step Solution:

1. **Understanding Pneumatophores**:
- Pneumatophores are specialized root structures that grow above the water surface. They are primarily found in hydrophytic trees, which are adapted to wet environments.

2. **Function of Pneumatophores**:
- The main function of pneumatophores is to facilitate aeration or ventilation. They help in the process of respiration, allowing the plant to take in oxygen from the air.

3. **Analyzing the Options**:
- The options provided are stomata, water pores, lenticels, and root hairs. We need to determine which of these structures are associated with pneumatophores.

4. **Evaluating Each Option**:
- **Stomata**: These are openings found on the leaves, regulated by guard cells, and are involved in transpiration. They are not present in pneumatophores.
- **Water Pores**: These are tiny pores found in the epidermis of leaves and young stems, not in pneumatophores.
- **Lenticels**: These are small openings in the bark of woody plants, including pneumatophores, that allow for gas exchange. They are essential for respiration in these structures.
- **Root Hairs**: These are extensions of root cells that help in the absorption of water and nutrients from the soil, not related to pneumatophores.

5. **Conclusion**:
- The correct answer is **lenticels**, as they are the structures present in pneumatophores that facilitate respiration in hydrophytic trees.

### Final Answer:
Pneumatophores possess **lenticels**.
