Question
Chapter 22.3, Problem 2MI
Summary Introduction
Gram-positive and gram-negative bacteria are differentiated based on the structural differences in the cell wall. Gram-negative bacteria consist of an outer membrane surrounding the thin peptidoglycan layer. Whereas, the gram-positive bacteria lack outer membrane and they have a thick peptidoglycan layer surrounding the plasma membrane.
