​Looking at cells and discovering the three parts of the cell theory wouldn't have been possible without the microscope. Cells are too small to see without a microscope.

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons

The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image.

A dissecting microscope is used to view three-dimensional objects and larger specimens, with a maximum magnification of 100x
