Vedclass · Answer

(D) Starch is a polysaccharide and is insoluble in water,which makes it an ideal storage molecule as it does not affect the osmotic potential of the cell.Plants transport carbohydrates from the leaves (source) to the storage organs like tubers (sink) in the form of sucrose,which is a soluble sugar.Once the sucrose reaches the tuber,it is converted into starch for long-term storage.Therefore,the starch is not transported directly; it is synthesized within the tuber from the incoming sugar solution.
