• A. True
• B. False

Answer 1

The correct option is B False

Chitinase helps in breaking down of chitin, the complex sugar which makes up the cell wall in fungi. It is the substance that is found protecting fungus and certain crustaceans. To break the cell wall of plant cells you need to use cellulase, since cellulose is the major constituent of plant cell wall.
