Simple Staining is Often Necessary to Improve Contrast in Which

Question

Simple staining is often necessary to improve contrast in which microscope?
A)compound light microscope
B)phase-contrast microscope
C)darkfield microscope
D)fluorescence microscope
E)electron microscope

Accepted Answer

Simple staining is a process where a single staining agent like methylene blue is used to enhance the contrast of the specimen. This is commonly done in the compound light microscope to make the details of the specimen more visible to the observer. Simple staining is not necessary in phase-contrast, darkfield, fluorescence, or electron microscopes as these microscopes are designed to enhance contrast without the need for staining.
