Questions and Answers

What does resolution measure in microscopy?

  • The magnification of the specimen
  • The ability to stain or label cell components
  • The measure of the clarity of the image, or the minimum distance of two distinguishable points (correct)
  • The contrast between different parts of the sample

    • Why is the resolution of standard light microscopy too low to study organelles?

  • The contrast between organelles and the surrounding sample is too low
  • The lenses are unable to refract light for organelle visualization
  • The magnification is not high enough to see organelles clearly
  • The minimum distance of two distinguishable points is not sufficient to study organelles (correct)

    • What is the main function of lenses in a light microscope?

  • Refract (bend) the light to magnify the image (correct)
  • Increase the resolution of the image
  • Stain or label cell components
  • Enhance contrast in the sample
