- Oh My! It looks like there are different colors of bacteria.

- You're right! These differences are the result of the composition of the cell wall. Some bacteria have peptidoglycan. These cells are called "gram positive?" bacterial cells.

- How does this have to do with the color of the bacteria?
- They get their color from a stain, whether violet and iodine, or methylene blue. Others, that do not contain peptidoglycan, are not stained and are referred to as gram-negative, and appear red.
