Observing Onion Cells Under The Microscope How to observe onion cells under a microscope. Onions are composed of several layers separated by thin membranes. In this activity, we will be using these thin membranes to observe onion cells in great detail. Obtaining a thin membrane from a bulb of onion is easy with the use of a pair of tweezers. For best results, use small, firm onions. Leaf Structure Under the Microscope When viewed under the microscope, it's possible to see the epidermal cells that tend to be irregular. In addition to the epidermal cells, one will also see the leaf spores (stomata) in between the epidermal cells. Typically, the stomata are bean shaped and will appear denser (darker) under the microscope. Biology Experiment Examination of Onion Cell in Light ...
