Which type of microscope would be most suitable for examining the surface structure of a virus?.
- A.Optical microscope
- B.Scanning electron microscope
- C.Transmission electron microscope
- D.Fluorescence microscope
Model answer
What a good answer should say
- Scanning electron microscope
Explanation
Why this works
A scanning electron microscope (SEM) is most suitable for examining the surface structure of a virus because it provides detailed three-dimensional images of the surface. Unlike optical microscopes, SEMs can achieve much higher resolutions and are capable of visualizing small structures like viruses.
Transmission electron microscopes (TEMs) are better for internal structures but require thin samples.
