Bumblebee removal occurs when bumblebees come in contact with the anthers of a flower while collecting nectar. When it enters a flower, the bumblebee's body hairs receive a dusting of pollen from the anthers. In queens and workers this is then groomed into the corbiculae (pollen baskets) on the hind legs where it can be seen as bulging masses that may contain as many as a million pollen grains. Male bumblebees do not have corbiculae and do not purposively collect pollen. Bumblebees are also capable of buzz pollination, in which they dislodge pollen from the anthers by creating a resonant vibration
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
