Verified by Toppr

Cellulose and starch both are polysaccharide carbohydrates found in plants.
A plant cell is characterized by a cellulosic cell wall, which is dead at maturity. Cellulose is made up of glucose molecules.
Starch is the storage polysaccharide, i.e. plants store their food in the form of starch. Starch is also made up of glucose.

So, the correct answer is 'Cellulose and starch'
