When looking looking through a microscope at many cells, try to focus on one spot. You'll notice that you can't focus clearly on all the cells at one time. That is because there are layers of cells on top of each other. You would have to change the focus of the lens to see each layer of cells. That how you can tell they have thickness and they aren't just flat when looking through a microscope.

Because different portions of them move in and out of focus as you adjust the 'scope. That means that the cells are too thick to be seen in one adjustment setting.
Another way would be to put your light source at the side, which would give you perception of depth that you don't get w/ bottom lighting.

cuz you only get a good view of whats inside them if you slice the cells themselves
