Explain how some plants are adapted for achieving pollination through wind. How vallisneria and seagrasses achieve pollination?

Explanation

Adaptations for achieving pollination through wind,
Pollination by wind is more-common amongst abiotic pollination and to achieve wind pollination, the pollen grains are light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens so that the pollens are easily dispersed into wind currents, and large, often-feathey sligma to easily trap air-borne pollen grains.
Wind pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence. A good example is the corn cob, where the tassels are nothing but the stigma and style which wave in the wind to trap pollen grains.
pollination in Vallisneria and seagrasses : In vallisneria, the female flowers each the surface of water by the long stalk and the male flowers or pollen grains are released onto the surface of water. They are carried passivewly by water currents. Some of them eventually reach the female flowers and the stigma. In another group of water pollinated plants such as seagrasses, female flowers remain submerged in water and the pollen grains are released inside the water. Pollen grains in many such species are long, ribbon like and they are carried passively inside the water. Some of themm reach the stigma and achieve pollination.
In most of the water - pollinated species, pollen grains are protected from wetting by a mucilaginous covering.
