Seeds dispersed by wind are

Options

A. Heavy
B. Round
C. Irregular
D. Light

Answer

**Step-by-Step Solution:**

1. **Understanding Seed Dispersal**: The process by which seeds are spread away from the parent plant is known as seed dispersal. Different methods of dispersal exist, including wind, water, and animals.

2. **Identifying Wind Dispersal**: When seeds are dispersed by wind, the term used is "anemocory." This means that the wind acts as the primary agent for spreading the seeds.

3. **Characteristics of Wind-Dispersed Seeds**: Seeds that are dispersed by wind typically have specific characteristics:
- They are **lightweight**: This allows them to be carried easily by the wind.
- They are often **small**: Smaller seeds can be lifted and transported more efficiently by wind currents.

4. **Exclusion of Other Options**:
- **Heavy seeds**: These would not be able to be carried by the wind effectively, so this option is incorrect.
- **Round seeds**: While some seeds may be round, this shape does not necessarily correlate with wind dispersal.
- **Irregular seeds**: Similar to round seeds, irregular shape does not define wind-dispersed seeds.

5. **Conclusion**: Based on the characteristics of seeds that are dispersed by wind, the correct answer is that they are **light**.

**Final Answer**: Seeds dispersed by wind are **light**.
