Question

Hypohydrophily Epitydrophily

Answer 1

Answer:

When pollination occurs in submerged plants, it is called hypohydrophily. For example, Ceratophyllum. In Ceratophyllum, the male flowers break and reach the surface of water and dehisce there. The pollen grains then sink in the water and come in contact with the stigma and pollination occurs under water.

Epihydrophily is a process of pollination in which the pollen grains are transferred from the surface of water whereas the hypohydrophily takes place below the water surface. Epihydrophily can be seen in plants that are grown above the surface of water whereas the hypohydrophily can be seen in submerged plants.
