BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Glucose is easily soluble in water, therefore, plants store glucose in the form of insoluble starch in leaves, root tubers, fruits, etc. Plants utilise this stored starch as a source of energy for life activities and prepare substances that are required for their growth.

Detailed explanation-2: -Plants store energy in the form of starch, instead of glucose, because starch is insoluble. This means that starch will not effect the water concentration inside cells and also it will not move away from the storage areas within the plant.

Detailed explanation-3: -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-4: -Foods such as potatoes, rice, corn and wheat contain starch granules which are important energy sources for humans. The human digestive process breaks down the starches into glucose units with the aid of enzymes, and those glucose molecules can circulate in the blood stream as an energy source.

Detailed explanation-5: -Glucose can be stored as starch. Plants can avoid this by converting the glucose into starch, an insoluble molecule. Starch is stored in the leaves, stem and roots of the plant. Starch can be used by the plant when it is not photosynthesising.
