Question

Algae have cell walls made up of

• A. Cellulose, Galactose and Mannose
• B. Hemi cellulose, Pectins and Proteins
• C. Pectins, Cellulose and Proteins
• D. Cellulose, Hemi cellulose and Pectins

Answer 1

Answer: (D)

Cellulose, Hemi cellulose and Pectins

• The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses, and pectin.
• Algae possess cell walls made of glycoproteins and polysaccharides such as carrageenan, cellulose, hemicellulose and pectins and agar that are absent from land plants. In bacteria, the cell wall is composed of peptidoglycan.
• Hence, Algae have cell walls made up of Cellulose, Hemicellulose, and Pectins.

So, the correct answer is 'Cellulose, Hemicellulose and Pectins'.
