Question

Algae have cell wall made up of

(a) cellulose, pectins and mannans

(b) hemicellulose, pectins and proteins

(c) pectins, cellulose and proteins

(d) cellulose, hemicellulose and pectins

Answer 1

Correct option  (a) cellulose, pectins and mannans

Explanation:

Algae have cell wall made up of cellulose, Galatians 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 additional 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 the walls of some red algae like Porphyra.
