Which of the following is incorrect for wind-pollinated plants?

Options

A. well exposed stamens and stigma
B. many ovules in each ovary
C. flowers are small and not brightly coloured
D. pollen grains are light and non-sticky

Answer

To determine which statement is incorrect regarding wind-pollinated plants, we can analyze each option based on the characteristics of these plants. Wind pollination, also known as anemophily, has specific traits that distinguish it from other forms of pollination.

### Step-by-Step Solution:

1. **Understanding Wind Pollination**:
- Wind-pollinated plants rely on the wind to transfer pollen from the male structures (stamens) to the female structures (stigmas). This process is known as anemophily.

2. **Evaluating Each Option**:
- **Option A**: "If there is a well-exposed stamens and the stigma."
- **Analysis**: This statement is correct. Well-exposed stamens and stigmas facilitate the transfer of pollen by wind.

- **Option B**: "Many ovules in each ovary."
- **Analysis**: This statement is incorrect. Wind-pollinated plants typically have a single ovule in each ovary, not many. This is a characteristic feature of these plants.

- **Option C**: "Flowers are small and not brightly colored."
- **Analysis**: This statement is correct. Wind-pollinated plants usually have small, inconspicuous flowers that do not need to attract pollinators, hence they are not brightly colored.

- **Option D**: "Pollen grains are light and non-sticky."
- **Analysis**: This statement is also correct. The pollen grains of wind-pollinated plants are light to be carried by air currents and non-sticky to avoid clumping.

3. **Conclusion**:
- Based on the evaluations, the incorrect statement regarding wind-pollinated plants is **Option B**: "Many ovules in each ovary."

### Final Answer:
The incorrect statement for wind-pollinated plants is **Option B: Many ovules in each ovary.**
