Pollen...?

how are pollen grains adapted for dispersal by wind?

Pollen...?
Pollen grains are small and lightweight, so they drift easily on the wind. Some, like pine pollen, actually have little wings.





Another adaptation for wind dispersal is that wind-pollinated plants make lots and lots of pollen. Way more than insect-pollinated plants make.
