What is a common application of optical microscopes that is not feasible with electron microscopes?.
- A.Studying cellular processes in real-time
- B.Analyzing the atomic structure of materials
- C.Visualizing the surface of nanoparticles
- D.Examining the internal structure of cells
Model answer
What a good answer should say
- Studying cellular processes in real-time
Explanation
Why this works
Optical microscopes can be used to study cellular processes in real-time because they allow for live specimens to be observed without the need for a vacuum. This is not feasible with electron microscopes, which require samples to be in a vacuum and often involve fixing or staining, thus preventing real-time observation of living cells.
