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 will analyze each option provided in the question.

### 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 characterized by certain adaptations in the plants.

2. **Analyzing the Statements**:
- **Statement 1**: "Well exposed stamens and stigma."
- **Analysis**: This is a correct statement. Wind-pollinated plants have their stamens and stigmas exposed to maximize the chances of pollen being carried by the wind.

- **Statement 2**: "Many ovules in each ovary."
- **Analysis**: This is an incorrect statement. Wind-pollinated plants typically have only one ovule per ovary. Having many ovules is more characteristic of other types of plants, such as those that are insect-pollinated.

- **Statement 3**: "Flowers are packed into inflorescence."
- **Analysis**: This statement is generally correct. Some wind-pollinated plants do have flowers that are packed into inflorescences to increase the chances of pollen dispersal.

- **Statement 4**: "Flowers are small and not brightly colored."
- **Analysis**: This is a correct statement. Wind-pollinated plants usually have small, inconspicuous flowers that do not need to attract pollinators, unlike insect-pollinated plants which are often brightly colored.

- **Statement 5**: "Pollen grains are light and non-sticky."
- **Analysis**: This is also a correct statement. The pollen grains of wind-pollinated plants are typically light and non-sticky, allowing them to be carried easily by the wind.

3. **Conclusion**: The only incorrect statement regarding wind-pollinated plants is "Many ovules in each ovary."

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