Answer: Option A.

Explanation:

Starch and cellulose are polymers of glucose and are formed by monomers of glucose joined together.

Starch is formed from alpha glucose, cellulose is formed from beta glucose.

Starch can be straight or branched and are use as energy storage by plants.

Cellulose molecules are linked and are rotated at 180degrees. Cellulose is the major constituents of plants cell. Humans cannot digest cellulose.

Answer: Option A. They have both polymers of glucose

Explanation:

Starch and cellulose are both polymers of glucose. They have similar structure, Starch and cellulose are two similar polymers. They are both made from the same monomer, glucose, and have the same glucose-based repeat units. They consists of long chains of glucose molecules connected to (1-4)-glycosidic bonds. Glycosidic bonds are the standard way of attaching things to glucose. The (1-4) bit simply means that the glucose molecules in the chain are connected to each other to the 1st and 4th carbon in the glucose ring opposite each other.
