In which type of flowers, stigma , is hairy and sticky?

Options

A. Insect pollinated
B. Wind pollinated
C. Water pollinated
D. All the above

Answer

To determine the type of flowers that have a hairy and sticky stigma, we can analyze the characteristics of different types of pollination.

### Step-by-Step Solution:

1. **Understanding Stigma Characteristics**: The stigma is the part of the flower that receives pollen. A hairy and sticky stigma is typically adapted to capture and hold pollen grains effectively.

2. **Analyzing Insect-Pollinated Flowers**:
- Insect-pollinated flowers often have larger and sticky pollen grains.
- However, the stigma in these flowers is usually not hairy; it is often smooth to facilitate the transfer of pollen from the insect to the stigma.
- **Conclusion**: This option is incorrect.

3. **Analyzing Wind-Pollinated Flowers**:
- Wind-pollinated flowers produce smaller, lighter pollen grains that can be carried by the wind.
- The stigma in these flowers is often hairy and sticky, which helps to catch the lightweight pollen grains as they are blown through the air.
- **Conclusion**: This option is correct.

4. **Analyzing Water-Pollinated Flowers**:
- Water-pollinated flowers rely on water currents for the transfer of pollen.
- The stigma in these flowers does not typically need to be hairy or sticky, as the mechanism of pollination is different.
- **Conclusion**: This option is incorrect.

5. **Considering the Option "All of the Above"**:
- Since we have established that only wind-pollinated flowers have a hairy and sticky stigma, this option is also incorrect.
- **Conclusion**: This option is incorrect.

### Final Answer:
The correct answer is **wind-pollinated flowers**.
