Starch and cellulose are very different from each other, but they share a striking similarity. Both are made of glucose monomers and hence called polysaccharides. Though made of glucose, both are bonded in different ways which give them different properties.
Starch dissolves in water while cellulose doesn’t. Cotton is made up of cellulose; it has a crystalline structure and stretches out. Just imagine what would happen to our cotton clothes if cellulose could be dissolved in water? It would disappear in the very first wash! Cellulose and its derivatives are widely used to make clothing and other things like paper, while starch is used for food.
