Epihydrophily takes place over the surface of water, e.g., Vallisneria. Reproduction: Questions 53-60 of 119. 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. Can you please help us? In Vallisneria male and female plants are separate. Epihydrophily : Plants which are pollinated outside the water.

For the present study we selected seven representative species representing all polli-nation types in the genus to investigate the effect of contact with water on pollen longevity. A special type of cleistogamy is found in flowers of legume plant. those considered historical (not seen in 20 years). Nutrients are dissolved in absorbed H2O. 1.  Hydrophily takes place only in few aquatic plants. (ii) Hypohydrophily:- When the pollination takes– place The female plant bears solitary flowers which rise to the surface of water level using a long coiled stalk at the time of pollination. D.
