Which microscope technique is best used for visualizing the surface structures of cells and viruses?

Question

Quizplus · Accepted Answer

Scanning electron microscopy (SEM) is the best choice for visualizing the surface structures of cells and viruses. SEM uses an electron beam to produce high-resolution, three-dimensional images of the surface of a specimen. This technique is particularly useful for examining the structure and morphology of small organelles, bacteria, and viruses. Phase-contrast microscopy is used to visualize the internal structures of cells that may not be visible under bright-field microscopy, while darkfield microscopy is typically used to observe live, unstained specimens.
