A specimen being viewed under a microscope should be thin so that light can pass, Otherwise the light cannot get through the specimen. Viewing specimens with a microscope: In most instances, light must pass through any object to be viewed with a light microscope. For this reason, an object to be viewed must be fairly thin. Thick objects may be sliced into thin sections for viewing.Why are they sometimes stained with dyes? (4 points) Specimens viewed with a compound microscope must be very thin, so that light can pass through them.
If they were not thin enough for light to pass through them, they would not be visible under a compound microscope. Some specimens are stained with dyes to help them become more easily visible and distinguishable. For example, cheek cells are often stained with methylene blue, to make individual cells more distinguishable from each other, and also to make the nucleus inside a cell distinguishable from the rest of the cell since this particular dye stains nucleic acids. Additionally, iodine is often used to stain plant cells to reveal the presence of starch.
