Compare and contrast gram - negative and gram - positive cell walls.

Question

Accepted Answer

∻Solution∻ ‖ a ⋮ Gram-positive cell walls: These have a thick peptidoglycan layer, which retains the crystal violet stain used in the Gram staining procedure, making them appear purple under a microscope. They also contain teichoic acids, which provide rigidity and can play a role in pathogenicity. ‖‖ b ⋮ Gram-negative cell walls: These have a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides (LPS). The outer membrane acts as an additional barrier, making Gram-negative bacteria more resistant to certain antibiotics. The LPS can also trigger strong immune responses in humans. ‖‖ c ⋮ Structural differences: The thick peptidoglycan layer in Gram-positive bacteria provides more structural support, while the outer membrane in Gram-negative bacteria offers additional protection and contributes to antibiotic resistance. ‖ ∻Answer∻ ⚹ Gram-positive cell walls have a thick peptidoglycan layer and teichoic acids, while Gram-negative cell walls have a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides. ⚹ ∻Key Concept∻ ⚹ Differences in cell wall structure between Gram-positive and Gram-negative bacteria ⚹ ∻Explanation∻ ⚹ Gram-positive bacteria have a thick peptidoglycan layer and teichoic acids, making them appear purple after Gram staining.
