Gram-positive and Gram-negative bacteria differ in their cell wall structure. Gram-positive bacteria have a thick peptidoglycan layer, while Gram-negative bacteria have a thinner peptidoglycan layer sandwiched between an inner and outer membrane. This difference impacts how the bacteria retains crystal violet dye used in the Gram staining protocol, determining whether it appears purple or pink under a microscope.
