Question

Algae have cell wall made up of:

• A. Cellulose, hemicellulose and pectins
• B. Cellulose, galactose and mannans
• C. Hemicellulose, pectins and proteins
• D. Pectins, cellulose and proteins

Answer 1

The correct option is B Cellulose, galactose and mannans

Algae is a diverse group of photosynthetic eukaryotes that possess a wide range of cell walls. While the algae typically possess walls made of glycoproteins and polysaccharides. The diatoms have a cell wall composed of biogenic silica. The red algal cell wall is made up of cellulose, xylan or mannin fibrils, the brown algae has cellulose and matrix polysaccharides.

So, the correct answer is 'Cellulose, galactose and mannans'
