Pollen in the scanning electron microscope

Below you see ...? Unfortunately we do not know exactly. We looked at an unknown mountain plant in REM. Because of its small size we assume that it is pollen, which was recorded in the scanning electron microscope (SEM) at 2500x magnification and on the right side at 7000x magnification.
On the left side you can see the pollen directly on the plant at approx. 700x magnification
