What is a function of a polysaccharide, like starch?
A
Stores energy
B
Movement
C
Stores genetic information
D
Speeds up reactions
Explanation: 

Detailed explanation-1: -They store energy in organisms. Due to the presence of multiple hydrogen bonds, the water cannot invade the molecules making them hydrophobic. They allow for changes in the concentration gradient which influences the uptake of nutrients and water by the cells.

Detailed explanation-2: -Glycogen: This polysaccharide is the polysaccharide found in animals to store energy and is composed of alpha-1, 4-glycosidic bonds with branched alpha-1, 6 bonds present at about every tenth monomer. It is mainly produced by the liver and muscles, but it can also be made during a process called glycogenesis.

Detailed explanation-3: -Starch is a storage polysaccharide in plants. It is a polymer consisting solely of glucose. Glucose is a source of fuel for cells; therefore, starch is stored for energy.
