Which of the following statements is a correct statement about bacteria cell walls?
In bacteria with acid-fast cell walls, there is an internal layer of mycolic acids beneath a thick peptidoglycan layer.
Gram-negative bacterial cell walls contain teichoic acids, whereas the cell walls of gram-positive bacteria do not.
The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria.
In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an external membrane made of phospholipids, lipopolysaccharides, and proteins.
What is the primary function of the two organelles that are believed to have evolved by endosymbiosis?
