(I) Our knowledge of cell structure took a giant leap forward as biologists began using the electron microscope in the 1950s. (II) Instead of light, the electron microscope (EM) uses a beam of electrons. (III) Actually, specimens should have been cut into extremely thin sections and stained with atoms of heavy metals such as gold. (IV) The EM has a much greater resolution than the light microscope. (V) Under special conditions, the most powerful EMs can detect individual atoms.
