Alstroemeria pollen grains, SEM. Alstroemeria pollen grains, coloured scanning electron micrograph (SEM). Pollen grains are reproductive structures produced by the male parts (anthers) of flowering plants. These pollen grains (orange) are on the anther (green) that produced them. This pollen is carried from one flower to another by pollinating insects. The pollen will then be transferred to the stigma, fertilizing the female parts (ova) to form the seed for a new plant.
