Answer
Monosaccharide is the simplest carbohydrates containing only one molecule of sugar. So it cannot be decomposed further into more sugar molecules. Example : Glucose and Fructose.
Disaccharide is a carbohydrate containing two monosaccharides joined by glycosidic linkage, and, on decomposition, it gives two monosaccharides. Example : Lactose and Sucrose.
Polysaccharides are carbohydrates formed by repeated chains of several monosaccharide. On decomposition, they form several units of monosaccharide. Example : Cellulose and Starch
