 This is an image of the epidermal layer of a green onion from Caltech’s open kitchen, taken 4/18/19 at 5PM. The sample was obtained by cutting and removing the thin, membrane-like layer between the thicker layers of the green onion. The layer was placed onto a slide with some water, and observed using the Foldscope. The elongated epidermal cells of the onion (Allium Fistulosum) can clearly be seen in the image. The cells are transparent and come in a single layer, which makes them easy to discern with the Foldscope. The tissue does not contain chloroplasts because the body of the onion is used for energy storage rather than photosynthesizing.

 These are images of a hibiscus flower pollen sample at different magnifications. The sample was obtained from a hibiscus bush located on the south side of Page House at Caltech at 4:00PM on May 10, 2019. The sample was obtained by dusting off pollen from the inside of a flower picked from the bush onto a glass slide. The plant was determined to be the rosa-sinensis species of the Hibiscus genus of the Malvaceae family.
