Question

(a) The cell wall of blue green algae is composed
of:
(1) Cellulose
ii) Cellulose and Glucan
(iii) Mucopeptide
(iv) Fucoidin​

Answer 1

Algae do have a cell wall which consists of cellulose, Galatians and mannans.

Algae, including plants, contain cell walls that comprise either polysaccharides like cellulose or a range of glycoproteins or both.

The presence of additional polysaccharides in algal cell walls is often used as a tool for algal taxonomy Mananas type microfibrils in the cell walls of a variety of marine green algae such as those in the genera Codium, Acetabularia and in the walls of certain red algae such as Porphyra.

In bacteria, the cell wall is composed of peptidoglycan.
