Question

Quizplus · Accepted Answer

Scanning electron microscopy (SEM) is particularly effective for creating images with a sense of depth because it scans the surface of specimens with a focused beam of electrons, producing detailed, three-dimensional images. It is not suitable for observing living specimens or examining internal cellular structures, as specimens must be coated with a conductive material and placed in a vacuum, which is incompatible with living conditions and internal examination.
