Some weeds, such as Australian sea grass and pond weeds, are pollinated by water. The pollen floats on water, and when it comes into contact with the flower, it is deposited inside the flower. Improperly treated sewage and agricultural run-off is finding its way into coastal waters, where the excessive levels of nitrogen in these contaminants is … TIE SEA-GRASSES OF THE WORLD . which shows aerial surface pollination. can be affected greatly by seasonal turbidity. Pollination-is the process by which pollen is transferred in plants, thereby enabling fertilization and sexual reproduction. 13 . The pinkish-green male flowers produce plenty of pollen, encased in long lines of slime. For the underwater-dwelling tape grass Enhalus acoroides, pollination is an adventure where female flowers have their work cut out.. Rhizomes may also be Females have stigmas shaped like tentacles, and the flower itself is supported by a coiled stalk. Hereby the pollen as well as the . pollen-grains and by the fact that its male flowers break off in the spathe The species is further peculiar in having large globular . Evolution Connection Pollination by Deception. styles remain dry. Flowering plants that grow in the ocean, known as seagrasses, are typically pollinated by the water itself. From this we can infer that wind-pollination originated millions of years before the grasses appeared on earth. Some weeds, such as Australian sea grass and pond weeds, are pollinated by water. Pollination by DeceptionOrchids are highly valued flowers, with many rare varieties . Climate 101: Oceans. The pollen floats on water, and when it comes into contact with the flower, it is deposited inside the flower. Along with wind pollination comes a reduction in perianth size and loss of pollen stickiness (Linder, 1998). In the case of sea grass, the female flowers remain submerged in water. Evolution Connection. Under the sea, however, things work a little differently. The grasses are wind-pollinated but so are all their relatives (Linder and Kellogg, 1995). When the largest dinosaurs were in their heyday, these grasses drifted from dry land into the sea. Figure 6. Among the marine Angiosperms Enhalus acoroides is the only species . A new study from Cardiff University has demonstrated that seagrass growth is suffering from exposure to pollution around the UK. A) In vallisneria and sea grass, pollination by water takes place b) In yucca, the moth deposits it's eggs in the locules of ovary and in turn the flower gets pollinated Rhizome- is a characteristically horizontal stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. The pollen grains are released inside the water. Cities, factories, and farms create waste, pollution, and chemical effluent and runoff that can wreak havoc on reefs, sea grasses, birds, and fish. The pollen grains are long, thread-like and are carried with the water and reach the stigma and achieve pollination. With the help of the water, the pollens come in contact with the female flowers and the pollination is achieved.
