What is a stain and what does a stain do when using one to view objects in the microscope?
A stain is a chemical that enhances the contrast ratio of microscopic items, such as individual structures in cells, so that those structures can be more readily observed in the microscope. The structures absorb the stain at different levels, making them stand out in the viewing field.
How is a microscope with slides used?
A microscope slide is the commonest instrument in any Biology laboratory. It is a transparent rectangular glass apparatus and it fits underneath the lens piece of the microscope. It is used for mounting smears of body secretions, microscopic specimen of bacteria, viruses, fungi or parasites. One can stain the specimen they want to observe and focus the microscope on it. A cover slip is placed on top of the slide in order to keep the specimen in place. One can use a microscope slide in order to draw blood films as well.
