Detailed explanation-1: -Starch is an insoluble, non-structural carbohydrate composed of -glucose polymers. It is synthesized by plants and algae to store energy in a dense, osmotically inert form.

Detailed explanation-2: -Glucose is made in photosynthesis and is transported around the plant as soluble sugar in the phloem. Much of the glucose is used in respiration and released as energy. However, glucose can also be converted into insoluble storage molecules – starch, fats & oils.

Detailed explanation-3: -In plants, glucose is stored in the form of starch, which can be broken down back into glucose via cellular respiration in order to supply ATP.

Detailed explanation-4: -Polymerisation. Glucose is converted into starch by the process called polymerization. In polymerization, several simple and soluble molecules of glucose are put together to form a complex, insoluble molecule of starch.
