Question

Cell wall is made up of: ____.

• A. Protein
• B. Lipid
• C. Cellulose
• D. DNA

Hint:

Different kingdoms have different cell wall building blocks! - Plants use Cellulose. - Fungi use Chitin. - Bacteria use Peptidoglycan.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The cell wall is a rigid, non-living outer layer that provides structural support, shape, and protection to plant cells, fungi, and some prokaryotes.

Step 2: Detailed Explanation:
In plants, the primary cell wall is predominantly composed of cellulose, a complex structural polysaccharide made up of linear chains of glucose units. Along with cellulose, the plant cell wall also contains matrix materials like hemicellulose, pectins, and structural proteins.
• Lipids and Proteins are the primary components of the flexible cell membrane (lipid bilayer), not the rigid cell wall.
• DNA is genetic material located inside the nucleus.

Step 3: Final Answer:
The plant cell wall is made up of cellulose.
