Pneumatophores are common in halophytes of saline swampy soil of sea shores for

Options

A. respiration
B. guttation
C. both (1) & (2)
D. Vivipary

Answer

**Step-by-Step Solution:**

1. **Understanding Pneumatophores**: Pneumatophores are specialized aerial roots found in certain plants, particularly halophytes, which thrive in saline and swampy conditions, such as those found on seashores.

2. **Function of Pneumatophores**: The primary function of pneumatophores is to facilitate respiration. These roots extend above the waterlogged soil, allowing the plant to take in oxygen from the air.

3. **Structure of Pneumatophores**: Pneumatophores are often pencil-like in shape and are negatively geotropic, meaning they grow upwards against the force of gravity. This adaptation helps them protrude above the waterlogged ground.

4. **Lenticels**: The surface of pneumatophores contains lenticels, which are small openings that allow for gas exchange. Through these lenticels, oxygen from the air enters the root and is transported to the rest of the plant.

5. **Conclusion**: Given their role in respiration and adaptation to saline, swampy environments, the correct answer to the question is that pneumatophores are common in halophytes for respiration.

**Final Answer**: Pneumatophores are common in halophytes of saline swampy soil of seashores for respiration.
