Gram-positive and gram-negative bacteria are differentiated based on their cell wall structure. Gram-positive bacteria possess a thick peptidoglycan layer in their cell wall, which retains the Gram stain, making them appear purple under a microscope. Gram-negative bacteria, on the other hand, have a thin peptidoglycan layer and an outer membrane, leading to the loss of the Gram stain and a pinkish or reddish appearance. This difference in cell wall structure has significant implications for bacterial physiology, susceptibility to antibiotics, and virulence.
