Question

Write note on hydrophily

Answer 1

Hydro means water and phily means affinity. Hydrophily are water pollinated plants. One example is Vallisneria.
The characteristics of water-pollinated plants are:
- Pollen grains are produced in large numbers.
-The weight of the pollen grains is equal to that of water. That is why they float on the surface of water.
-The pollen grains continue to float on the surface of water till they meet the female flowers. The same procedure is followed in the water pollinated flower called Vallisneria.

Answer 2

Hydrophily is a fairly uncommon form of pollination whereby pollen is distributed by the flow of waters, particularly in rivers and streams. Hydrophilous species fall into two categories: (i) Those that distribute their pollen to the surface of water. e.g. Vallisneria's male flower or pollen grain are released on the surface of water, which are passively carried away by water currents; some of them eventually reach the female flower (ii) Those that distribute it beneath the surface. e.g. seagrasses in which female flower remain submergered in water and pollen grains are released inside the water.
