Solution
Starch involves alpha glucose whereas cellulose involves beta glucose. Thus both are homopolysaccharides made up of glucose.
Both starch and glucose are mainly found in plants.
Starch contains 1,6 glycosidic bonds whereas cellulose only contains 1,4 glycosidic bonds Thus they both have glycosidic bonds.
Starch forms a coiled/helical structure whereas cellulose forms a linear fibre. Thus only starch can hold iodine. Thus option 3 is not a similarity and hence the answer.
