Question

gram negative bacteria do not take a stain give reason​

Answer 1

Answer: Due to differences in the thickness of a peptidoglycan layer in the cell membrane

Explanation:

Due to differences in the thickness of a peptidoglycan layer in the cell membrane between Gram positive and Gram negative bacteria, Gram positive bacteria (with a thicker peptidoglycan layer) retain crystal violet stain during the decolorization process, while Gram negative bacteria lose the crystal violet stain and are instead stained by the safranin in the final staining process.
