I bought a bouquet of lilies for my mother on her birthday, and a day later, its anthers started dehiscing.
I made a slide of the pollen, and viewed it the next morning. The pollen grains appear to have a very good resolution, and the pattern on the exine is quite visible.
I was then interested in finding out the size of the pollen, since they seemed to have swollen since my last observation.
I cut a few cross-sections of the stigma, and I could see that they had irregular sizes. The nucleus was quite prominent in all these observations.
Its great seeing the little things around us become so vivid and detailed under the foldscope.
