Plants, which produce characteristic pneumatophores and show vivpary belong to

Options

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

Answer

To solve the question regarding which type of plants produce characteristic pneumatophores and show viviparity, we can analyze the options provided:

1. **Understanding the Terms**:
- **Pneumatophores**: These are specialized aerial roots that help plants obtain oxygen in waterlogged conditions. They are typically found in certain types of wetland plants.
- **Viviparity**: This refers to a reproductive strategy where seeds germinate while still attached to the parent plant, allowing for immediate establishment in suitable environments.

2. **Analyzing the Options**:
- **Option A: Mesophytes**:
- Mesophytes are plants that thrive in environments with moderate water availability. They do not produce pneumatophores and do not exhibit viviparity.
- **Conclusion**: This option is incorrect.

- **Option B: Halophytes**:
- Halophytes are plants that grow in saline (salt-rich) environments, such as salt marshes and mudflats.
- They are known to produce pneumatophores to help them access oxygen in waterlogged soils and they can exhibit viviparity, where seeds germinate while still attached to the parent plant.
- **Conclusion**: This option is correct.

- **Option C: Semaphytes**:
- Semaphytes are plants that grow in sandy or desert environments. They are adapted to dry conditions and do not typically produce pneumatophores or exhibit viviparity.
- **Conclusion**: This option is incorrect.

3. **Final Conclusion**:
- Based on the analysis, the plants that produce characteristic pneumatophores and show viviparity belong to **Halophytes**.

**Answer**: Option B: Halophytes.
