Answer 2

Compound light microscope: Light illuminated. Two dimensional images. This microscope is the most commonly used. You can view individual cells, even living ones. High magnification, but a low resolution. Specimens are placed on glass slides and are seen through light absorption.

Transmission electron microscope: Electron illuminated. Has a 2-D view. Thin slices of specimen are obtained. The electron beams pass through it and seen by means of electron scattering. It has high magnification and high resolution. Specimens are mounted on thin films of collodion or other supporting material on copper grids.
