QUESTION 15 Why is crystal violet used in the Gram stain retained in the cell wall of Gram positive bacteria, but not in Gram negative bacteria? Gram positive bacteria have a thick peptidoglycan layer while Gram negative bacteria have a thin peptidoglycan layer. Gram positive bacteria form spores and Gram negative do not. O Gram positive bacteria have no peptidoglycan layer and Gram negative bacteria have a thick cell wall O Gram positive bacteria have capsules and Gram negative bacteria...
