You are doing research on a bacterial species, trying to determine the shape, distribution, and arrangement of a number of filamentous structures that protrude from the cell surface.Which type of microscopy would best enable you to do this?
A)scanning electron microscopy
B)transmission electron microscopy
C)bright-field microscopy
D)dark-field microscopy

Question

Quizplus · Accepted Answer

Scanning electron microscopy is the best choice as it provides high-resolution images of the surface of cells, allowing for the visualization of filamentous structures that protrude from the cell surface. This microscopy uses a focused beam of electrons to scan the cell surface, producing a 3D image of the specimen. Transmission electron microscopy is better suited for studying internal structures of cells, while bright-field and dark-field microscopy do not provide sufficient resolution for visualizing filamentous structures.
