One of the easiest, simplest, and also fun ways to learn about microscopy is to look at onion cells under a microscope. As a matter of fact, observing onion cells through a microscope lens is a staple part of most introductory classes in cell biology – so don't be surprised if your laboratory reeks of onions during the first week of the semester.
