In what form is food stored in organisms of Kingdom Fungi?

Correct answer: Glycogen and oil

Direct answer: B is correct. Fungi are heterotrophic organisms that absorb nutrients from their surroundings. They do not usually store their reserve carbohydrate as starch, the characteristic storage carbohydrate of plants. Instead, fungal cells commonly store reserve food as glycogen and lipid or oil droplets. Glycogen is also an important storage carbohydrate in animals, which is a useful comparison. A is wrong because starch is chiefly associated with plant storage, although it may occur in particular contexts outside plants; it is not the standard answer for fungi. C is wrong because cellulose is a structural component of many plant cell walls, not the usual reserve food of fungi. D is wrong because proteins have many functions but are not identified as the principal reserve food form in this question. Memory cue: plants store starch; fungi and animals are associated with glycogen, and fungi also store oil.
