Answer #1

Components of Gram positive Cell Wall	Components of Gram Negative Cell Wall
Consists of many layers of peptidoglycan(60-90%).	Contains only one layer of peptidoglycan layers(10-20%).
Consists of Techoic acids and Lipotechoic Acids.	Outer membrane is composed of phospholipids, lipopolysaccharides and proteins. Pore forming proteins called porins span the outer membrane.

Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. 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 outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...
