Gram-positive bacteria have thicker cell walls that retain the purple color from Gram stain, which can quickly differentiate cell types based on the width of their cell walls.

Differences between gram-positive and gram-negative bacteria. All bacteria have a cell wall composed of mesh-like strands of a big molecule called peptidoglycan, which surrounds the cell membrane.
