Some fruits—for example, the dandelion—have hairy, weightless structures that are suited to dispersal by wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float. Coconuts are well known for their ability to float on water to reach land where they can germinate.

Dandelion and Cotton have hairy seeds/fruits which are dispersed by wind.
Explanation:
- Seed is the mature ovule of flowering plants from which a new plantlet emerges.
- Seeds of the plants are dispersed by various agents after fertilisation.
- Seed dispersal involves the movement of seeds from the parent plant to some other places.
- Seed dispersal agents include wind, water, animals and birds. Based on the nature of the seeds, the seed movement takes place.
- Seeds that are dispersed by wind have lightweight that helps the seeds to float in the air.
- Some tall trees produce seeds with wings, some other produce hairy outgrowth, the rest of the plants make seeds with feathery tails.
- These properties enable the seeds to move from one place to another by wind.
