A gram-negative cell wall consists of_________
omeli [17]

Answer:

The correct answer is D. A gram-negative cell wall consists of a thin layer of peptidoglycan surrounded by an outer membrane containing lipopolysaccharides.

Explanation:

Gram-negative bacteria are bacteria that do not retain the gentian violet dye during the Gram staining protocol.

During the Gram staining process, a contrast dye, usually safranin, is added after gentian violet, causing the Gram negative bacteria to stain pink or red. The contrast dye thus allows the visualization of Gram-negative bacteria which, because they have a thinner layer of peptidoglycans, cannot retain the gentian violet dye.

Its main feature is an endotoxin called lipopolysaccharide that causes pathogenicity and is responsible for its virulence.
