Question

Quizplus · Accepted Answer

The cell wall of Gram-positive bacteria contains a thick layer of peptidoglycan, which makes it structurally different from the cell wall of Gram-negative bacteria. This thick layer of peptidoglycan is responsible for the Gram-positive bacteria's ability to retain the crystal violet stain during the Gram-staining process.
