In vallisneria, the female flower reach the surface of water by the long stalk and the male flower or pollen grains are released into the surface of water. pollinators in some plant species. Fertilization is a process in which male and female gametes fused to form the zygote. The cell division during embryogenesis is mitotic in diploid organisms. In asexual reproduction, variation may occur due to mutation whereas variation occurs due to mutation, crossing over and recombination in sexual reproduction. This will help us to improve better. In most of the water pollinated plants there is a mucilaginous covering on the pollen grains which protect it from wetting. In Zostera, the marine angiosperm (Sea Grass), the pollen grains are long ribon-like (upto 2500 mm) and without exine. Maximum loss of pollen grains takes place only in this pollination. ii) Epihydrogamous: The pollination taking place along the surface of the wateje.g. The lower lip functions as sitting pad for insects. After fertilization, offsprings are produced large in number but no parental care is provided. Books. Pollination occurs in submerged condition by water.
