- Cellulose
- Hemicellulose
- Cellulose and hemicellulose
- Peptidoglycan
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Bacterial cell wall is made up of peptidoglycan.It is composed of a long chain of alternating sugar molecules of N-acetylglucosamine NAG and N-acetylmuramic acid NAM.Peptidoglycan layer helps in the protection of the bacteria from osmotic pressure.Gram positive bacteria have a thicker peptidoglycan layer and appear purple when stained.On the other hand, the gram negative bacteria have a thinner peptidoglycan layer.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
