Answer 2

• As the pollination of Vallisneria puts up with using water, the pollen grains are covered by a mucilaginous layer that safeguards the pollen from water.

• In Vallisneria, the female flower enters the surface of the water by the long stalk and the male flower or pollen grains are discharged into the surface of the water.

• They are held up by water currents entering the female flowers and the stigma.
