Question

A major breakthrough in the studies of cells came with the development of electron microscope. This is because:

• A. the resolution power of the electron microscope is much higher than that of the light microscope
• B. the resolving power of the electron microscope is 200 – 350 nm as compared to 0.1 – 0.2 nm for the light microscope
• C. electron beam can pass through thick materials, whereas light microscopy requires thin sections
• D. the electron microscope is more powerful than the light microscope as it uses a beam of electrons which has wavelength much longer than that of photons

Answer 1

Answer: (A)

the resolution power of the electron microscope is much higher than that of the light microscope

Answer 2

The electron microscope has a significantly higher resolution compared to the light microscope, allowing researchers to visualize much smaller structures and details within cells. This increased resolution is due to the shorter wavelength of electrons compared to photons (light), which enables the electron microscope to distinguish finer structural features.

So, the correct option is (A): the resolution power of the electron microscope is much higher than that of the light microscope.
