"Most bacteria can be broadly classified as Gram positive or Gram negative.
Gram positive bacteria have cell walls composed of thick layers of peptidoglycan.
Gram positive cells stain purple when subjected to a Gram stain procedure.
Gram negative bacteria have cell walls with a thin layer of peptidoglycan. The cell wall also includes an outer membrane with lipopolysaccharide (LPS) molecules attached."
