Why do wind pollinated plants have large feathery stigma?

Wind-pollinated plants:

1. Wind pollination is the process in which pollen is distributed by wind.
2. Such plants do not possess flowers, nectar, and scent as they do not require pollinating organisms.
3. Wind-pollinated plants produce large numbers of light, dry pollen that are easier to carry by the wind.
4. Stigma is the topmost surface of the pistil that receives pollen grains.
5. Wind-pollinated flowers have a large, feathery stigma in order to trap the airborne pollen grains.
6. Examples of plants that participate in wind pollination are wheat, rice, corn, and barley.
