Respuesta :

As gram-negative bacteria have an extra layer of cell wall therefore it is less sensitive towards antimicrobial chemicals than gram-positive bacteria.

Why gram-positives are less impervious to the action of antimicrobial chemicals?

Gram-positive bacterial cell wall is made up of only the peptidoglycan layer and it does not have an extra barrier that protects it from some antimicrobial chemicals.

Gram-negative bacteria have two layers of cell wall peptidoglycan layer and a lipopolysaccharide layer.

Thus, gram-negative bacteria have an extra layer of cell wall.
