Question

How is pollination carried out in water plants?

Answer 1

Hint: Pollination is the process of collecting pollen grains from a flower's male component, the anther, and moving them to the female component, the stigma. Pollen grains must be transported from the same species of flower in order for pollination to be successful. Pollination begins when pollen grains from the respective flowers land on the stigma and create a pollen tube the length of the style that joins the stigma and the ovary. The pollen grain begins transporting sperm cells from the grain to the ovary after the pollen tube is completed.

Complete answer:
Water, wind, and insects are all used to pollinate water plants. Water pollination occurs in a few plants, such as Vallisneria, Hydrilla, and Zostera (seagrass), among others. Pollen grains on water pollinated plants are protected by a mucilaginous coating. Most aquatic plants, such as water hyacinth and water lily, are pollinated by wind or insects. Flowers emerge from the water's surface and are pollinated in the same way that land plants are pollinated.
Water-mediated pollination occurs in only a few plants. The female bloom of Vallisneria reaches the water's surface. Pollen grains are strewn across the water's surface and are carried to the female flower for pollination via passive transport. The female flower of seagrass remains immersed in water, and pollen grains are dispersed below the water's surface. Pollen grains contain a mucilaginous coating that prevents them from becoming wet when pollinated by water.

Note:
Types of pollination:
Self-pollination- Because only one flower is involved, it is referred to as primary pollination. Pollen grains fall directly from the anther into the stigma of the flower, resulting in self-pollination. Because the flower's sperm and egg cells share some genetic information, this procedure is simple and quick, resulting in a decrease in genetic variety.
Cross pollination- It's a complicated method of pollination that allows pollen grains to be transferred from one flower's anther to the stigma of another. As various flowers share and integrate their genetic information to make unique offspring, this strategy increases genetic variety.
