Question

question 21. which microscope would a scientist use if they wanted to see the outside surface of a prokaryotic cell in detail? a. transmission electron microscope b. scanning electron microscope c. dissecting microscope d. compound light microscope

Explanation:

Scanning Electron Microscopes (SEMs) are used to visualize the surface structure of specimens. They work by scanning the surface with a focused beam of electrons and detecting the electrons that are scattered or emitted from the sample's surface, providing detailed images of the outside surface of objects like prokaryotic cells. Transmission Electron Microscopes (TEMs) are for internal structures. Dissecting microscopes and compound light microscopes do not have the resolution to see prokaryotic cell - surface details at the level an SEM can.

Answer:

B. Scanning Electron Microscope
