Inulin, a storage polysaccharide found in some plants, differs from starch in several key aspects. Which of the following statements accurately describes a major difference between inulin and starch?
Inulin is a branched polymer, while starch is strictly linear.
Inulin is primarily found in animals, while starch is found in plants.
Inulin forms a helical structure, while starch forms a sheet-like structure.
Inulin is composed of fructose units linked by β(2→1) glycosidic bonds, while starch primarily consists of glucose units linked by α(1→4) and α(1→6) bonds.

Why doesn't cellulose react with iodine to produce a blue color?
It lacks the helical structure necessary for iodine complexation.
It contains fructose units instead of glucose.
It is a branched polymer and cannot interact with iodine.
It is insoluble in water, preventing the reaction with iodine.
