Explain the difference between a simple stain and wet mount technique. When would each be
indicated for use. - ANSWERS-- Simple Staining uses solutions of methylene blue, crystal violet,
safranin or fuchsin to bind to and stain membranes or microorganisms. Used to quickly observe
the size, shape and arrangement of cells.
- Wet mount uses a small liquid culture containing a sample that is added to the slide and is
used to observe the motility of an microorganism
