Question
Answer the following question.
Express the process of pollination in Vallisneria.
Solution
Vallisneria grows in freshwater and is pollinated by water. It is a type of pollination known as hydrophily. The female flowers reach the surface of the water by a long stalk while the pollen grains are released on the surface of the water. These are passively carried by water currents to reach the stigma of the female flowers. Pollen grains of such plants are covered by mucilage which protects them from wetting.
