Question

why fungi cell wall is made up of chitin?

Answer 1

Chitin is a polysaccharide which helps the cell walls of the fungus to penetrate plants and animals, for breaking them down and extracting nutrients. Therefore fungi cells are made up of chitin.

Answer 2

chitin supports and protect the delivate soft tissues of the organisms, which lack an internal skeleton. The chitin adds rigidity and structural support to the thin cells walls of the fungus,and makes fresh mushroom crisp.
