Quizplus · Accepted Answer

The Gram stain differentiates between Gram-positive and Gram-negative cells based on differences in their cell walls. Gram-positive cells have a thick peptidoglycan layer which retains the crystal violet stain, while Gram-negative cells have a thinner peptidoglycan layer with an outer membrane that contains lipopolysaccharides which prevent the crystal violet stain from entering, but retain the counterstain safranin.
