HUMAN NUTRITION

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: -Glucose produced by photosynthesis is easily soluble in water and it can’t be stored in plant. Plants store glucose as starch in leaves which is insoluble and is utilized as a source of energy for life activities growth.

Detailed explanation-3: -Starch is a chain of glucose molecules which are bound together, to form a bigger molecule, which is called a polysaccharide.

Detailed explanation-4: -The starch in non-photosynthetic tissues, such as seeds, stems, roots or tubers, is generally stored for longer periods and regarded as storage starch. Remobilization takes place during germination, sprouting or regrowth, again when photosynthesis cannot meet the demand for energy and carbon skeletons for biosynthesis.
