This is an image of the cell structure of allium cepa, or red onion. At the same magnification as the other vegetables, the individual onion cells are larger, measuring in around 200µm. There is no tint to these, as the specimen was taken from the central part. Onion provided a good specimen for this project, as since the onion naturally layers, and since the color is semi-transparent, a thin layer was able to be taken by peeling. This thin layer was then cut to fit on a slide, and used as a sample. The onion sample was obtained from the north house open kitchen salad bar, using tongs, at 2:11pm on 5/30.
