Question

Sucrose is highly soluble in water. It is also relatively inactive metabolically. Suggest how these two properties make it suitable as a long distance transport sugar.

Accepted Answer

The glucose is formed by photosynthesis is transported into different parts of the cell through the phloem. Phloem consists of different types of cells. The translocation takes place through the sieve tubes. The organic nutrients transport through the sieve tube in the form of sucrose which is a disaccharide composed of glucose and fructose. The sucrose is transported in solution in the phloem sap in plants. It occurs through a mass flow that takes place by the entry of sucrose and subsequently water in the sieve tube. Hence, high solubility and low viscosity make transportation easily. Sucrose is a non-reducing sugar that is not oxidized. It has no reducing end and is thus, considered a more inert material. Hence, it cannot form other products during transport.
