Which of the following is adaptation for anemophily ?

Options

A. Presence of nectar
B. Hairy stigma
C. Sticky pollen
D. Fragrance

Answer

To determine which of the following is an adaptation for anemophily (pollination by wind), we need to analyze the options provided: presence of nectar, hairy stigma, sticky pollen, and fragrance.

### Step-by-Step Solution:

1. **Understanding Anemophily**:
- Anemophily is a type of pollination where pollen is transferred from the male part (anther) to the female part (stigma) of a flower through wind.

2. **Characteristics of Anemophilous Plants**:
- Pollen grains are usually light and non-sticky to facilitate their movement through air currents.
- The stigma is often large and feathery to effectively capture and trap pollen grains carried by the wind.
- The stamens are well exposed to allow for easy dispersal of pollen into the air.

3. **Analyzing the Options**:
- **Presence of Nectar**: This is an adaptation for insect pollination (entomophily), as nectar attracts insects.
- **Hairy Stigma**: A hairy or feathery stigma is beneficial for capturing pollen grains from the wind, making it suitable for anemophily.
- **Sticky Pollen**: Sticky pollen is not suitable for wind pollination, as it would not disperse easily in the air.
- **Fragrance**: Fragrance is also an adaptation for attracting insects, not for wind pollination.

4. **Conclusion**:
- The adaptation for anemophily among the given options is the **hairy stigma**. This feature helps in trapping pollen grains effectively as they are carried by the wind.

### Final Answer:
- The adaptation for anemophily is **hairy stigma**.
