Clematis and Naravelia are dispersed by air with the help of

Options

A. Peristent inflated calyx
B. Perisistent hairy styles
C. Hair
D. Wings

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Dispersal**: Seed dispersal is crucial for plants as it helps them avoid competition, colonize new areas, and promote genetic diversity among populations.

2. **Identifying the Plants**: The question specifically mentions two plants: Clematis and Naravelia. Both of these plants rely on air for seed dispersal.

3. **Analyzing Dispersal Mechanisms**: For seeds to be effectively dispersed by air, they need to be lightweight and have structures that facilitate their movement through the air.

4. **Evaluating the Options**:
- **Option 1: Persistent Inflated Calyx**: This structure is small and thin, which would not aid in seed movement. Thus, this option is incorrect.
- **Option 2: Persistent Hairy Styles**: These structures can help seeds float in the air, making them a viable option for dispersal.
- **Option 3: Hair**: While hair can assist in movement, it is not as effective as the combination of light seeds and hairy styles for air dispersal.

5. **Conclusion**: The persistent hairy styles of Clematis and Naravelia are specifically adapted to aid in their dispersal by air. These structures allow the seeds to float and travel long distances due to their light weight and the presence of hairs.

6. **Final Answer**: Clematis and Naravelia are dispersed by air with the help of **persistent hairy styles**.
