Hydrophily (Water Pollination): (Gk, Hydro = water and Philein = to love) Hydrophily takes place only in few aquatic plants. Pollination is a process in which pollen is transferred to the female reproductive organs of seed plants, thereby enabling fertilizationand reproduction through growth of the pollen tube and eventual release of sperm. Pollination in plants is the process where pollen is transferred from the anther, the male part of a flower, to the stigma, the female part of a flower. The female flower have a very long pedicel, therefore it reaches the surface of water. About 80% pollination occurs by insects like moths, beetles, butterflies, wasp, etc. (i) Epihydrophily: When the pollination takes place on the surface of water, it is called epihydrophily.

Clipping is a handy way to collect important slides you want to go back to later. E?—/ûpüýz‚Ââcñáø Hydrophily is of two kinds: hypohydrophily and epihydrophily. Hydrophily (Water Pollination): (Gk, Hydro = water and Philein = to love) Hydrophily takes place only in few aquatic plants. Pollination is a process in which pollen is transferred to the female reproductive organs of seed plants, thereby enabling fertilizationand reproduction through growth of the pollen tube and eventual release of sperm. Pollination in plants is the process where pollen is transferred from the anther, the male part of a flower, to the stigma, the female part of a flower. The female flower have a very long pedicel, therefore it reaches the surface of water. About 80% pollination occurs by insects like moths, beetles, butterflies, wasp, etc. (i) Epihydrophily: When the pollination takes place on the surface of water, it is called epihydrophily.
