Pneumatophores are found in plants growing in swampy areas. Such roots are seen in-

Options

A. Zamikand
B. Colocasia
C. Alstonia
D. Rhizophora

Answer

**Step-by-Step Solution:**

1. **Understanding Pneumatophores**: Pneumatophores are specialized aerial roots that help plants obtain oxygen in waterlogged or swampy environments. They are adapted to facilitate gas exchange.

2. **Identifying the Environment**: These roots are typically found in swampy areas where the soil is saturated with water, making it difficult for plants to access oxygen from the soil.

3. **Characteristics of Pneumatophores**: Pneumatophores are negatively geotropic, meaning they grow upwards against gravity, and positively phototropic, meaning they grow towards light. This adaptation allows them to protrude above the water level.

4. **Identifying the Plant**: The specific plant known for having pneumatophores is Rhizophora, which is a genus of mangrove trees. These trees thrive in coastal intertidal zones and are well adapted to the saline and waterlogged conditions.

5. **Conclusion**: Therefore, the correct answer to the question is that pneumatophores are seen in Rhizophora.

**Final Answer**: Pneumatophores are found in Rhizophora.
