Plants, which produce characteristic pneumatophores and show vivpary belong to

Options

A. Mesophytes
B. Halophytes
C. Psammophytes
D. Hydrophytes

Answer

To solve the question "Plants, which produce characteristic pneumatophores and show vivipary belong to," we need to analyze the terms and options provided.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Pneumatophores**: These are specialized aerial roots that grow above the ground. They are typically found in swampy areas and help in gas exchange through structures called lenticels.
- **Vivipary**: This term refers to a condition where seeds germinate while still attached to the parent plant, meaning the seeds start to grow before they are dispersed.

2. **Analyze the Options**:
- **Option A: Mesophytes**: These plants thrive in moderate water conditions and do not produce pneumatophores. Therefore, they cannot be the answer.
- **Option B: Halophytes**: These are plants that grow in high salinity conditions, such as salt marshes, and they often produce pneumatophores. They can also exhibit vivipary, as seen in species like Rhizophora.
- **Option C: Samophytes**: These plants are adapted to dry conditions, such as deserts, and do not produce pneumatophores. Hence, this option is incorrect.
- **Option D: Hydrophytes**: These plants live in water bodies and do not typically produce pneumatophores. Therefore, this option is also incorrect.

3. **Conclusion**:
- Based on the definitions and characteristics of the options, the only group of plants that produce pneumatophores and show vivipary is **Halophytes**.

Thus, the correct answer is **Halophytes**.
