-scanning electron microscopy (SEM)

A) utilizes a thin beam of electrons to examine structures within a cell
B) utilizes lasers to scan a fluorescently stained specimen; a computer focuses the light to show a single plane through a cell
C) utilizes differences in the way light is bent (refraction) in areas of various cellular density to visualize living cells
D) requires light passing through the specimen; typically involves staining with dye to enhance contrast; usually "fixes" and kills the cell
E) a beam of electrons scanned over a whole cell allows visualization of surface structures; gives a 3D-appearing image
