Potato tubers Storage method

Starch is not a pure substance. The term refers to a group of polysaccharides found in plants. Starches serve as a major method of food storage in plant seeds and tubers. Corn, potatoes, wheat, and rice all contain substantial amounts of starch. These plant products serve as major sources of needed food energy for humans. Enzymes in the digestive system catalyze the hydrolysis of starch to glucose. 

Starch is a storage substance of plants and is deposited abundantly in seeds (grain) and tubers (potatoes, etc.) in the form of granules. Two types of compounds can be distinguished by chemical methods.
