How is pollen transported in grasses and with many trees?

Pollen in grasses and many trees is primarily transported by wind, a process known as anemophily. Grasses produce lightweight, dry pollen grains that can be easily carried over long distances by air currents. Similarly, many trees, such as pines and oaks, release large quantities of pollen into the atmosphere, allowing it to be dispersed to female reproductive structures for fertilization. This adaptation enhances cross-pollination and increases genetic diversity.
