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.
