For each of the following items, state: "Gram " if it is seen in just Gram positive bacteria, "Gram - " if it is seen just in Gram negative bacteria, or "both" if it is seen in both Gram positive and Gram negative bacteria.

1) A cell wall that is made of peptidoglycan

2) A cytoplasmic membrane composed of phospholipids and protein

3) An outer membrane that includes lipopolysaccharide (LPS)

4) A thick cell wall that causes the bacteria to be purple in the Gram stain

5) Teichoic acids and lipoteichoic acids embedded in the cell wall

6) A thin cell wall that causes the bacteria to be red in the Gram stain

    1) A cell wall that is made of peptidoglycan BOTH

    2) A cytoplasmic membrane composed of phospholipids and protein BOTH

    3) An outer membrane that includes lipopolysaccharide (LPS) GRAM-

    4) A thick cell wall that causes the bacteria to be purple in the Gram stain GRAM+

    5) Teichoic acids and lipoteichoic acids embedded in the cell wall GRAM+

    6) A thin cell wall that causes the bacteria to be red in the Gram stain GRAM-

    Both of them have peptidoglycan layer in their cell wall, but the one in Gram + is thick (multilayered), while the one in Gram - is thin. This is the reason why the crystal violet dye retain in the walls of Gram + causing them to be purple (Gram - stay red). Gram - are more resistant against antibodies because of their impenetrable cell wall.
