Swelling in the feet and ankles is a very common symptom and can have a variety of causes. One way that doctors pinpoint the cause of swelling is by noting whether it is occurring in one limb, or in both equally. In many cases, the cause of swelling is something that requires medical attention, such as an infection or injury.
Pollination and Fertilization of Plants Visit a flower garden in the summer and youâll see and hear lots of activity. Bees are buzzing and busily moving from flower to flower.
Pollination takes place immediately before the anthesis. Anthers elevate by elongating the stamen filaments, and untimately they go out the spikelet during anthesis. When anthers touch stigma, some pollen are left on the stigma. The stigma can receive pollen also during the flowering, when the spikelet opens.
