A major break through in the studies of cells came with the development of electron microscope. This is because :
  1. (a) The resolution power of the EM is much higher than that of light microscope
  2. (b) The resolving power of the EM is as compared to for the light microscope
  3. (c) Electron beam can pass through thick materials, whereas light microscopy requires thin sections
  4. (d) The EM is more powerful than the light microscope as it uses a beam of electrons which has wavelength much longer than that of protons.
