Wind is a correct answer because the light weight of this plant is easily move and dispersed...

Seed Dispersal Mechanisms:
There are several mechanisms through which seeds are dispersed in nature. Light, small, and dry seeds are specifically adapted for dispersal by wind.
Wind Dispersal Mechanism:
- Wind dispersal, also known as anemochory, is a common mechanism for dispersing seeds.
- This mechanism is especially effective for light and small seeds that have adaptations to catch the wind and travel over long distances.
- The main adaptations of wind-dispersed seeds include lightweight structures and structures that enable them to be carried by air currents.
- Some key characteristics of wind-dispersed seeds are feathery or wing-like structures, hairs, or parachutes that increase buoyancy and enable them to be lifted and carried by the wind.
- As the seeds are released from the parent plant, they can be carried away by the wind to new locations, increasing their chances of germination and survival.
Examples of Wind-Dispersed Seeds:
- Dandelion seeds have a fluffy structure called a pappus that allows them to be easily carried by the wind.
- Maple tree seeds, also known as samaras or "helicopters," have wing-like structures that spin and glide in the air, aiding in their dispersal.
- Milkweed seeds have silky hairs that help them float in the wind.
- The seeds of pine trees have wings called "pine cones" that enable them to be carried by the wind.
In conclusion, light, small, and dry seeds are dispersed by the wind. Their adaptations allow them to be easily carried away from the parent plant to new locations, increasing their chances of survival and successful germination.
