Question

which is not a way in which light microscopes and electron microscopes differ?
a the image resolution of electron microscopes has allowed us to see clearer images of the microscopic world than we can view with light microscopes.
b light microscopes can magnify an image to about 1000 times. electron microscopes can magnify images 100’s of thousand, if not millions, of times.
c light microscopes cannot be used to view living organisms. metals, such as gold, must be when preparing the slides for reflection of the light.
d light microscopes use light energy, either natural or artificial, to create the magnified image being viewed. electron microscopes use electrons, not photons or light rays, for visualization

Explanation:

• Option A: Electron microscopes have higher resolution than light microscopes, so this is a difference.
• Option B: Light microscopes have lower magnification (around 1000x) compared to electron microscopes (hundreds of thousands to millions of times), so this is a difference.
• Option C: Light microscopes can be used to view living organisms (they don't require metal coating like electron microscopes, and electron microscopes can't view living organisms as the preparation process kills them). Also, the statement about metals being used for light microscopes is incorrect (metals are used in electron microscope sample preparation for imaging). So this is not a valid difference.
• Option D: Light microscopes use light (photons) and electron microscopes use electrons, so this is a difference.

Answer:

C. Light microscopes cannot be used to view living organisms. Metals, such as gold, must be when preparing the slides for reflection of the light.
