C. pectins, cellulose and proteins
D. cellulose, hemicellulose and pectins

Answer

A

Explanation

(a) Algae have cell wall made up of cellulose, galactans and mannans. Like plants, algae have cell walls containing either polysaccharides such as cellulose (a glucan) or a variety of glycoproteins or both. The inclusion of additionnal polysaccharide in algal cell walls is used as a feature for algal taxonomy. Mananas form microfibrils in the cell walls of a number of marine green algae including those from the genera Codium, Acetabularia as well as in thte walls of some red algae like Porphyra.
