Seed dispersal
An important detail for a wind-dispersed seed is that it is very light. It must be able to float easily on wind or else it will drop straight to the ground. There are "parachutes" on top of some seeds, like milkweed and dandelion seeds. Some seeds are very small and light, almost like dust. Orchid seeds and poppy seeds are like that. Poppy seeds are inside a little capsule that has little openings around the top. On a windy day, the poppy fruit capsule will sway from side to side, shaking out the tiny seeds out the windows like a salt shaker.
