I made a cast of marigold leaves (using clear nail polish) to observe the stomata under a Foldscope 2.0. These little "mouths" that "breathe" for the leaves never cease to amaze me!

These images are at 140X plus 5X digital zoom on my phone. The first 2 are from the front of the leaf and the last 3 are from the back of the leaf.
