WebEffective pollination involves the transfer of pollen from the anthers to a stigma of the same species and subsequent germination and growth of the pollen tube to the micropyle of the ovule. Pollen transfer is effected by wind, water, and animals, primarily insects and birds. WebIn many aquatic plants with emergent flowers, pollination occurs by wind or insects, e.g., Lotus, Water Lily, Water Hyacinth. Hydrophylly is of two types— hypohydrophily and epihydrophily. Hypohydrophily occurs below the surface of water, e.g., Zostera, Ceratophyllum. Epihydrophily takes place over the surface of water, e.g., Vallisneria.
