How does a transmission electron microscope TEMdiffer from a scanning electron microscope SEM?

ATransmission Electron Microscope produces an image by transmitting or "shooting" electrons through an ultra thin slice of the sample, resulting in cross section views of the thing you're looking at.
A Scanning Electron Microscope produces 3D images of the sample by bombarding it with electrons and measuring the ones that bounce off.
An important difference is that an ETM has much more magnifying power than a SEM, because of the amount of electrons accelerated towards the sample.
