Starch and cellulose molecules differ in structure primarily because starch is composed of α-glucose units, while cellulose is made of β-glucose units, with a difference in the orientation of functional groups on the first carbon.
Starch and cellulose differ in structure because starch is made from α-glucose while cellulose is made from β-glucose, with an inverted position of hydrogen and hydroxyl groups on carbon 1.
