Description: Caption:
Under a magnification of 98X, this scanning electron microscopic (SEM) image revealed some of the ultrastructural features found amongst a collection of pollen found within the dehisced, or ruptured, anther of a yellow sundrops, Oenothera fruticosa flower. Note the pod-like configuration of the anther, within which reside many pollen grains, ready for dissemination into the passing wind, or to be attached to a pollinator, such as a bee. Judging by the shape of these pollen grains, it appears that the majority had yet to dry, for the elliptical, football-shaped grains, closer to the lip of the anther, represented those that had dried, while the rounder grains represented those that were still moist.
