Cell the Unit of Life question

2006 · Q59

NEETBiologyCell the Unit of LifeMCQ+4 / −1
A major breakthrough in the studies of cells came with the development of electron microscope. This is because
  1. A
    Electron beam can pass through thick materials, whereas light microscopy requires thin sections
  2. B
    The resolution power of the electron microscope is much higher than that of the light microscope
  3. C
    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
  4. D
    The resolving power of the electron microscope is 200-350 nm as compared to 0.1-0.2 nm for the light microscope
View written solutionFree

Correct answer: D

Microscopes are used for studying cellular structures. They are used to magnify small objects. In electron microscopes, a high energy beam of electrons is focused through electromagnetic lenses. It can magnify very small details with high resolving power. The increased resolution results from the shorter wavelength of the electron beam.
