For my biology homework I have to write about three types of microscopes, their features, advantages and disadvantages. So far, using my textbook, I have found out about the light microscope and electron microscope but I am unsure about the third one. Does anybody know about the third one, its features, advantages and disadvantages?

Not sure what you need but this is what I know. The three types of microscope are light microscopes, transmission electron microscopes (TEM) and scanning electron microscopes (SEM). Light microscopes have the smallest resolution of 200 nam due to the limit of the wavelength of light. Cells under this microscope can be alive or fixed and stained. TEMs have a better resolution of 2nm (the same as SEMs). TEMs look at replicas of dead cells after fiction and heavy metal ion staining (this is also the same for SEMs)
Hopefully this helps.
