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: -Starch polymer made up of glucose monomers Most plants store energy as starch. Starch is a polymer made up of many glucose monomers joined together in a chain. Starch is insoluble, it forms grains inside the cell to keep itself separate. Fats and oils are better molecules for storing energy in many ways.

Detailed explanation-3: -Glucose is stored as polymeric glucan, in animals as glycogen and in plants as starch.

Detailed explanation-4: -Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source. That’s why some foods that we eat, like rice and grains, are packed with starch!

Detailed explanation-5: -Plants make, and store temporary supplies of starch in their leaves, which they use during the night when there is no light available for photosynthesis.
