Cell wall of algae is made up of

CONCEPT:

Cell Wall Composition in Algae

• The cell wall is an essential structural component of algae and provides support, protection, and shape to the cell.
• The composition of the cell wall varies among different groups of algae, but it commonly includes polysaccharides such as cellulose, galactans, and mannans.
• Cellulose is a structural polysaccharide, while galactans and mannans are other polysaccharides that contribute to the unique properties of algal cell walls.

EXPLANATION

• Cellulose is a common structural polysaccharide found in the cell walls of many algae.
• Galactans are polysaccharides made of galactose units, often found in red algae (e.g., agar).
• Mannans are polysaccharides made of mannose units, contributing to the structure in certain algae.

Additional Information

• Peptidoglycan is found in bacterial cell walls, not algae.
• Hemicellulose is common in higher plants but is not a primary component of algal cell walls.

Therefore, the cell wall of algae is made up of cellulose, galactans, and mannans.
