Detailed explanation-1: -Starch is a polysaccharide carbohydrate (C6H10O5)n consisting of a large number of glucose monosaccharide units joined together by glycosidic bonds found especially in seeds, bulbs, and tubers.

Detailed explanation-2: -Monosaccharides contain a single unit; disaccharides contain two sugar units; and polysaccharides contain many sugar units as in polymers-most contain glucose as the monosaccharide unit.

Detailed explanation-3: -Polysaccharides include carbohydrates that are made of three or more sugars. The prefix ‘poly’ means ‘many, ‘ and the root word ‘saccharide’ means ‘sugar’. So, a polysaccharide is a carbohydrate made of many sugars. Starch and glycogen are two of the most common types of polysaccharides.

Detailed explanation-4: -Depending on the number of carbon atoms, the carbohydrate may be a triose, tetrose, pentose or hexose. Disaccharides contain two sugar units. Oligosaccharides contain 3 to 10 sugar units. Polysaccharides contain more than 10 sugar units.

Detailed explanation-5: -polysaccharide, also called glycan, the form in which most natural carbohydrates occur. Polysaccharides may have a molecular structure that is either branched or linear.
