Weegy: Electron Microscopes (EMs) function exactly as their optical counterparts except that they use a focused beam of electrons instead of light to 'image' the specimen and gain information as to its structure and composition. [ A stream of electrons is formed and accelerated toward the specimen using a positive electrical potential. The stream is confined and focused using metal apertures and magnetic lenses into a thin, focused, monochromatic beam. Interactions occur inside the irradiated sample, affecting the electron beam. ] User: The invention of the microscope made it possible for people to discover User: Ranjeet is studying an unknown group of cells and finds that the cells have lysosomes.
