1. Gram Stain What should be the color after the gram stain? What should be the morphology or shape? Explain why the bacterium will give these results. 2. MacConkey Agar What are the expected results (growth and color) on MacConkey agar. Will the bacterium grow on this media? If it can grow, what is the color of colonies? Explain why the bacterium will give these results.

Step 1
Gram Stain: The color after the gram stain depends on whether the bacterium is gram-positive or gram-negative. - If it is a gram-positive bacterium, the color will be **purple**. - If it is a gram-negative bacterium, the color will be **pink**. The morphology Show more…

Describe in detail why the Gram stain procedures stain Gram + bacteria purple, and Gram - bacteria pink. DO NOT JUST SAY "THICK OR THINNER CELL WALL". I want to know the detailed specifics of the steps that result in WHY this procedure stains cells differentially. Think and find out the mechanisms of how each of the procedures.

a. Describe the gram staining process and explain what makes the cell stain gram positive. b. Would the hemolysis process (breakdown on red blood cells) on the blood agar plates make blood agar selective or differential media and explain why.
