Large polysaccharides generally have one of two functions: as a very strong structural component of a cell and as a storage molecule for readily accessible energy. There are also two primary energy-storage polysaccharides. What are they?

A) Starch, which is synthesized by plants, and glycogen, which is synthesized by animals.

B) Glucose, which is synthesized by plants, and glycogen, which is synthesized by animals.

C) Cellulose, which is synthesized by plants, and glycogen, which is synthesized by animals.

D) Starch, which is synthesized by plants, and phospholipids, which are synthesized by animals.

A) Starch, which is synthesized by plants, and glycogen, which is synthesized by animals.

Both compounds are carbohydrate polymers, but are composed of different compounds. Starch is actually a mixture of two slightly different polysaccharides while glycogen is essentially amylopectin. (explanation from USATestprep)
