Detailed explanation-1: -A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons.
Detailed explanation-2: -SEMs use electrons to magnify objects up to two million times their actual size. Transmission electron microscopes, or TEMs, produce 2D black-and-white images of a cell’s ultrastructures and cellular organelles.
Detailed explanation-3: -SEMs provide a 3D image of the surface of the sample, whereas TEM images are 2D projections of the sample, which in some cases makes the interpretation of the results more difficult for the operator.
Detailed explanation-4: -Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes.
Detailed explanation-5: -Freeze-fracture electron microscopy provides a way of visualizing the interior of cell membranes.
