Question

Which of the following is/are made up of cellulose?

• A. Cell membrane
• B. Plasma membrane
• C. Cell wall
• D. All of the above

Answer 1

The correct option is C Cell wall

In a plant cell, the non-living layer secreted by protoplasm which forms a protective layer around the living plasma membrane is called cell wall. Chemically, the plant cell wall is made up of cellulose, hemicellulose, pectin, lignin, glycoproteins and various kinds of chemical substances. Cellulose is a complex polysaccharide which is made up of β(1→4) linked D-glucose units. Thus option C is the correct answer.
