What is gram staining?
Gram Staining is a way to separate one large groups of bacteria into two. Crystal violet is used to dye the cells, those that retain the color are grouped as Gram-positive, and those that do not retain the color are grouped as Gram-negative. Many of the Gram-negative bacteria are pathogenic, making this process useful for detecting infections. A link is provided to permit a quick trip to the Wikipedia article on this topic.
Thin clear rectangular pieces of glass upon which specimens are mounted before being viewed under a microscope?
The piece of glass used to observe specimens under a microscope is called a slide. Sometimes a thin piece of glass is used to cover the specimen. This is called a coverslip. Coverslips and slides can be made of glass, quartz or plastic, as long as these items are totally transparent and do not introduce any distortion. Sometimes the material may be tinted in order to add contrast, although this is usually done with dye.
