Questions and Answers

What is the main advantage of confocal laser-scanning microscopy (CLSM) compared to standard brightfield microscopy?

  • Limited spatial resolution
  • Ability to capture very dynamic cellular processes (correct)
  • Efficiency in capturing deep into thicker specimens
  • Higher magnification capabilities

How are images obtained with standard fluorescence microscopy different from those obtained with confocal laser-scanning microscopy (CLSM)?

  • They have higher spatial resolution in CLSM images.
  • CLSM captures images at a lower magnification than standard fluorescence microscopy.
  • CLSM excludes out-of-focus fluorescence from the specimen. (correct)
  • Standard fluorescence microscopy captures more dynamic processes than CLSM.

How does super-resolution CLSM differ from standard CLSM in terms of spatial resolution?

  • Both super-resolution and standard CLSM have similar spatial resolutions.
  • Super-resolution CLSM has spatial resolution about 10 times better than standard CLSM. (correct)
  • Standard CLSM has better spatial resolution than super-resolution CLSM.
  • Super-resolution CLSM has spatial resolution about 10 times worse than standard CLSM.
