Question

Vallisneria spiralis is a classical example of

• A. Epihydrophily
• B. Hypohydrophily
• C. Anemophily
• D. Chiropterophily

Answer 1

Answer: (A)

Epihydrophily

Pollination is the transfer of pollen from a male part of a plant (anther) to a female part of a plant (stigma), enabling later fertilisation and the production of seeds, most often by an animal or by the wind. Hydrophily is a fairly uncommon form of pollination whereby pollen is distributed by the flow of waters, particularly in rivers and streams. Epihydrophily is a pseudo hydrophily that occurs on the surface of the water. Vallisneria pollen grains are released on the surface of the water, which are passively carried away by water currents; some of them eventually reach the female flower.

So the correct option is 'epihydrophily'.
