Answer 2

elecrons instead of light act as the source of illumination.

A tungsten filament and anode plays the role of electron gun.

condenser and obective lens are actually the electromagnetic lens used in the EM.

The Final image is obtained on a flurescent screen which can be imprinted on a photographic plate.

A copper grind holds the specimen. The whole apparatus is maintained in vacuum so that the electrons are not scattered.

In Scanning electron microscope the deflected secondary electrons are captured by an amplifier and detector to process the image on the computer screen while in transmission EM the electrons which are obtained after passing throught the thinly cut specimen is responsible for the image formation.
