I recently came across a flower, with pink petals, and a conical strcuture as the central whorl full of small and minute stamen. I couldnt pluck the flower, but using the forceps, I took out a bunch of stamen. I observed distinctly the filament, and also while observing the anther, I saw certain portions with spherical pollen grain still inside the pollen sac. It was insightful to look at the structures and learn in greater depth.

I had some wuestions, like in the picture of the single pollen grain, is the smaller darker structure the nucleus, or the generative cell within the vegetative cell.
