Why do scientists stain slides when looking at them?
October 17, 2011 9:34PM
Bacteria are difficult to see when they are not stained because they are almost colorless.
1. Staining a slide enables a high contrast between the bacteria and the background.
2. It defines the bacterial morphology (size, shape and arrangement).
3. It enables us to observe structures like flagella, capsules and endospores.
