Description: Caption:
Under a magnification of 1648X, this scanning electron microscopic (SEM) image revealed some of the morphologic ultrastructure displayed by a number of pollen grains found within the dehisced, or ruptured, anther of a yellow sundrops, Oenothera fruticosa flower. These pollen grains were of the tricolpate type of pollen, which means that their outer surface was traversed from pole to pole, by three symmetrically placed furrows. The textured surface also identified these grains, as the reticulate type. Note the round shape of these grains, indicating that they had yet to undergo a drying process, in order to become ready to be disseminated into the plants environment.
