- Peptidoglycan
- Cytoplasmic membrane
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The stain is retained by the peptidoglycan layer within the cell wall of the bacteria. They are classified into gram positive and gram negative. Gram positive has a thick layer of peptidoglycan, that prevents the stain from washing away. Gram negative on the other hand, has a thin layer of peptidoglycan.
