What are two functions of polysaccharides?
A
Storage and Energy
B
Energy and Structure
C
Structure and Storage
D
Structure and Protection
Explanation: 

Detailed explanation-1: -Polysaccharides generally perform one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage. Cellulose and chitin are linear polymers that are used for structural support in plants and animals, respectively.

Detailed explanation-2: -Storage polysaccharides are those that are used for storage. For instance, plants store glucose in the form of starch. Animals store simple sugars in the form of glycogen. Structural polysaccharides are carbohydrates that have a structural role.

Detailed explanation-3: -There are two main storage polysaccharides-starch and glycogen.

Detailed explanation-4: -Answer and Explanation: A storage polysaccharide is any polysaccharide that is used to store energy. The examples of a storage polysaccharide in plant cells is starch. A structural polysaccharide is any type of polysaccharide that forms the structural framework of a cell.

Detailed explanation-5: -Polysaccharides consist of a succession of covalently linked monosaccharides (Shelke et al., 2014). The building blocks of 10 or more monosaccharide units are joined together by 1, 4-glycosidic bonds to form cross-linked high–molecular weight polysaccharides.
