Flower wind to move pollen from one flower to the next. Examples include grasses, birch trees, ragweed and maples. They have no need to attract pollinators and therefore tend not to be "showy" flowers. Male and female reproductive organs are generally found in separate flowers, the male flowers having a number of long filaments terminating in exposed stamens, and the female flowers having long, feather-like stigmas. Whereas the pollen of animal-pollinated flowers tends to be large-grained, sticky, and rich in protein (another "reward" for pollinators), anemophilous flower pollen is usually small-grained, very light, and of little nutritional value to animals. The
Thalassia testudinum flowers open. There are two methods of pollination: hydrophily and biotic pollination. Through hydrophily, the pollen grains are carried through the water column by tides or currents and deposited upon an open pistillateflower. More recent investigation however, has uncovered active biotic pollination.Underwater video cameras have revealed that Crustacean, Polychaete, and Amphipoda swam towards open male flowers. These creatures were attracted to the seagrass’s nutritious mucilage—a carbohydrate-rich substance that houses pollen. As the invertebrates feeds on the mucilage, excess pollen grains stick to their bodies. They move from flower to flower feeding and spreading the pollen from male to female. Seeds
