Figure 5.3 Looking at Cells The first six images below show some techniques used in light microscopy. The last three images were created using electron microscopes. All of these images are of a particular type of cultured cell known as HeLa cells.

Note that the images in most cases are flat, two-dimensional views. As you look at images of cells, keep in mind that they are three-dimensional structures.
