similarities and differences between gram-positive and gram-negative bacteria.

rue or False: All bacteria can be classified as either gram-positive or gram-negative.

Gram PositiveGram-positive bacteria have a thick outer layer composed primarily of peptidoglycan, constituting about 90% of their cell wall. On the other hand, Gram-negative bacteria possess a chemically complex, thinner, and less compact cell wall, with peptidoglycan accounting for only 5-20% of the structure. Importantly, in Gram-negative bacteria, peptidoglycan is situated between the plasma membrane and the outer membrane, making it less accessible to antibiotics.
