Quizplus · Accepted Answer

Gram-positive bacteria have a thicker layer of peptidoglycan in their cell walls compared to gram-negative bacteria. This is what allows them to retain the crystal violet stain in the gram-stain procedure, giving them their characteristic purple color. Gram-negative bacteria have a thinner layer of peptidoglycan in their cell walls, but have an outer membrane that contains lipopolysaccharides which can trigger an immune response and cause inflammation and fever. Gram-positive bacteria do not have an outer membrane.
