Wind-pollination is quite common

Options

A. in grasses
B. in lilies
C. in orchids
D. in tropical forests

Answer

**Step-by-Step Solution:**

1. **Understanding Wind Pollination**: Wind pollination, also known as anemophily, is a process where pollen is transferred from the male part of a flower (stamen) to the female part (stigma) through the wind. This method is common in certain types of plants.

2. **Characteristics of Wind-Pollinated Plants**:
- **Exposed Stamens**: Wind-pollinated plants have well-exposed stamens to facilitate the dispersal of pollen grains by wind currents.
- **Feathery Stigmas**: The stigmas of these plants are often long and feathery, which helps in trapping the pollen carried by the wind.
- **Flower Appearance**: The flowers of wind-pollinated plants tend to be small, dull-colored, and lack fragrance. This is because they do not need to attract pollinators, as their pollination relies solely on wind.

3. **Examples of Wind-Pollinated Plants**:
- Grasses are a prime example of plants that utilize wind pollination. They have the characteristics mentioned above, making them well-suited for this type of pollination.
- Other plants like lilies and orchids are not wind-pollinated; they have colorful and fragrant flowers that attract pollinators.

4. **Identifying the Correct Option**:
- Among the options provided, grasses are the most common examples of wind-pollinated plants. Therefore, the correct answer to the question is "grasses."

**Final Answer**: The common example of wind-pollination is grasses.
