After building my Foldscope, I set out to investigate how and where plants store pigment in their leaves and petals to give them their characteristic color, as well as release water. Thus, I went into the garden around my house in Claremont, CA, and took samples of several leaves and petals from different kinds of trees. I took one leaf from a rosebush and another leaf from a bougainvillea vine and investigated both of them under my foldscope. Interestingly enough, I found that despite the different pigments between the rosebush leaf and bougainvillea petal, they both stored pigment in the same matter. Furthermore, I discovered small tiny holes in both the bougainvillea petal and rosebush leaf that made them appear translucent, and I hypothesized that these tiny holes were the stromata that regulated the amount of water that was with the petals and leaves at one time. Below are pictures of what I saw in my microscope.
