Question

what is the chemical characteristic of algal cell wall and fungi cell wall​

Answer 1

In general, algal cell walls are made up of two components:

(1) the fibrillar component, which forms the skeleton of the wall, and

(2) the amorphous component, which forms a matrix within which the fibrillar component is embedded.

The most common type of fibrillar component is cellulose, a polymer of 1,4 linked -D-glucose. Cellulose is replaced by a mannan, a polymer of 1,4 linked -D-mannose, in some siphonaceous greens, and in Porphyra and Bangia in the Rhodophyta.
