HUMAN NUTRITION

Detailed explanation-1: -Plants store glucose as starch in leaves which is insoluble and is utilized as a source of energy for life activities growth.

Detailed explanation-2: -Glucose Structure Starch and cellulose are both made of glucose molecules. Glucose is a monosaccharide and is essential for many functions inside the cell. Glucose is the primary source of energy for the process of cellular respiration, which makes ATP, or cellular energy.

Detailed explanation-3: -Glucose dissolves readily in water and it can pass through the cell membranes in response to concentration gradients. In order to store glucose in one location, plants must condense it to a water-insoluble form. Starches are glucose polymers that contain 300-1000 glucose units.

Detailed explanation-4: -Glucose is stored as polymeric glucan, in animals as glycogen and in plants as starch. Despite serving a general source for metabolic energy and energy storage, glucose is the main building block for cellulose synthesis and represents the metabolic starting point of carboxylate-and amino acid synthesis.
