Lignin and cellulose provide rigidity to the cell walls of plants. But in most fungi, chitin performs this role. Why is it logic
WARRIOR [948]

Answer:

Fungi most fungi produce cellulases.

Explanation:

Fungi are eukaryotic microorganisms, however unlike other eukaryotes. Their cell wall is made up of chitin instead of cellulose.

Chitin is a fibrous polysaccharide found in the exoskeleton of arthropods and the cell wall of fungi.  where as cellulose is also a polysaccharide which is an important structural component of plant cell wall.

Since fungi are saprophytic they produce enzymes such as cellulases that will help in breakdown of cellulose for food.

They cannot have a cell wall made of cellulose.
