3)Peptidoglycan is thicker and multilayered
4)Techoic acids are present in their cell walls.
5)Lipopolysaccharides are absent in their cell wall.
6)No periplasmic space present
Gram negative bacteria :
1) They retain red safaranin stain thus stain pink.
2)They produce both exotoxins as well as endotoxins.
3)Peptidoglycan is thinner and single layered.
4)Techoic acids are absent in their cell walls.
5)Lipopolysaccharides are present in their cell wall.
6)Periplasmic space in present.
