Briefly explain how a Scanning Electron Microscope (SEM) forms an
image of subcellular organelles, substrates, and viral particles. - ANSWER An image is
formed from the interactions of electrons
as they reflect off (not through) the surface of the specimen.
Samples are coated in either gold or palladium to enhance
electron reflections. The reflection is seen in 3-D rendering.
OR
A scan (image) as electrons reflect off surfaces of a specimen loaded into the machine. In or-
der for this to best work, any sample is coated in gold or other refractive material to en-
hance reflections. SEM is shown in 3-D
