Answer
Cellulose , starch and glycogen are different common polysacchrides. They have repeating glucose units. The way glucose units are bonde.d determines their type. cellulos the oxygen atoms are roughly p.allel with the plane of the rings called $B$-glycosidic linkage. in starch and glycogen, the oxygen atoms join neighbouring glucose units poi. down relative to the planes of the rings and is named as a glycosidic linkage.
