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.
