Algae have cells made up of (a) cellulose, galactans and mannans (b) hemicellulose, pectins and proteins (c) pectins, cellulose and proteins (d) cellulose, hemicellulose and pectins.
Option A Majority of algae (eukaryotes) possess a definite cell wall containing cellulose and other carbohydrates. In algal cell wall, different chemical components are present which vary widely among different groups (e.g., xylan, mannan, galactan, alginic acid, silica, agar, pectin, carrageenin, etc.). Cell wall of bluegreen algae is made up of micropeptides (proteins). This micropeptide is not found in eukaryotic algae.
