Correct Answer: Starch

Solution : The correct option is Starch .

Starch is a naturally occurring polymer made up of glucose molecules. It is a complicated carbohydrate that is the principal energy storage molecule in plants. Long chains of glucose units are joined together by glycosidic bonds to form starch molecules. These glucose units can be organised in two ways: linear amylose, and branching amylopectin. Starch is an important source of energy for both plants and animals. Other naturally occurring polymers are Protein, Polysaccharides, Starch, Nucleic acids etc.
