I’m a little too excited because of this pictures. These pictures were taken of a sorus (the brown thing on the leaf) of a fern throw the foldscope and when I first saw them I had no idea of what was I looking at, but I knew I was going to know later because of my Botany classes. Now I know that those things are called leptosporangia and are structures that have many spores inside and that help the fernos to reproduce.
