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: -Some glucose is used for respiration, while some is converted into insoluble starch for storage. The stored starch can later be turned back into glucose and used in respiration.
Detailed explanation-3: -Starch is insoluble in water so won’t affect the way water moves in and out of the plant, meaning plants can store large amounts of starch in their cells. Starch molecules are very large so they cannot move out of the cell. This means they can act as energy stores.
Detailed explanation-4: -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-5: -Plants store starch because these carbohydrates are a way of preserving energy for later use. They trap glucose as part of the carbohydrate compound and break off smaller glucose units when they need to consume more energy than they readily have available through photosynthesis.
