Description: Caption:
Under a magnification of 1648X, this scanning electron microscopic (SEM) image revealed some of the morphologic ultrastructure found amongst a collection of pollen contained 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 the outer surface was traversed from pole to pole, by three symmetrically placed furrows. The textured surface also identified this grain as of the reticulate type. Note that the grains' shape was elliptical, indicating that they had undergone a drying process, and were ready to be disseminated into the plant’s environment.
