Dispersal of Seeds by the Wind - The Seed Site
Seeds that can fly or glide. Some tall trees produce seeds with stiff wings covering the seed that enable them to fly long distances. The wings are twisted and balanced so that the seed spins around as it is carried along by the wind.
Innovative plant: How does the dandelion drift its seeds?
