Answer:

Starch has several properties that make it an excellent form of energy storage for plants.

Explanation:

  • Starch is insoluble.

This has two consequences:

(a) The starch granules do not move away from the storage areas in the plant.

(b) Starch has little effect on osmotic pressure, so it does not disrupt the water balance in the cell.

  • The starch molecule is compact .

Starch molecules are coiled into compact single and double helices.

That means they can pack more energy into less space than glucose can.

  • Starch provides good bioavailability of glucose.

Starch molecules are easily converted back to glucose when needed by the cell.

The small glucose molecules are soluble and easily transported to the locations where they are needed.
