How do Gram-negative bacteria differ from Gram-positive bacteria?
How do Gram-negative bacteria differ from Gram-positive bacteria?
Gram-negative bacteria have a thicker cell wall
Gram-negative bacteria have a thinner cell wall
Gram-negative bacteria have a different type of cell wall
Gram-negative bacteria do not have a cell wall
Solution
Gram-negative bacteria differ from Gram-positive bacteria in the structure of their cell walls. Gram-negative bacteria have a thinner cell wall, which is composed of a thin peptidoglycan layer, surrounded by an outer membrane containing lipopolysaccharides. This thinner cell wall makes it harder for the gram stain to penetrate and for the bacteria to retain the crystal violet dye.
