1-starch is a Storage Polysaccharide but cellulose is a Structural Polysaccharide .
2-starch has two forms :Amylose (unbranched) and Amylopectin (somewhat branched) but cellulose has only unbranched form
3-monomers of starch are α glucose but monomers of cellulose are β glucose .These two interconvertible forms of glucose differ in the placement of the hydroxyl group attached to the number 1carbon.
