Vedclass · Answer

(D) Plants transport carbohydrates from source (leaves) to sink (storage organs like potato tubers) in the form of sucrose through the phloem. Once sucrose reaches the potato tuber,it is converted into starch,which is an insoluble polysaccharide. This polymerization of sucrose into starch is advantageous because it creates an osmotic gradient that allows more sucrose to flow into the tuber,and it serves as an efficient,compact form of energy storage.

Starch is insoluble in water,yet it is accumulated in large quantities in potato tuber because
