</span>Polysaccharide are the complex form of carbohydrates.
A starch molecule is formed when many disaccharide molecules are combined. Starch is often produced in plants as a means of storing energy. The two other molecules formed when multiple disaccharide molecules are combined are cellulose and glycogen. The cell walls in plants are made up of cellulose. Glycogen is a carbohydrate energy source.
A disaccharide molecule is formed when two monosaccharide molecules are joined together. Maltose, sucrose and lactose are the most important disaccharides. <span>A monosaccharide molecule is a simple sugar, for example, glucose. </span>
During cellular respiration, glucose and oxygen<span> are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration. Respiration is also the process by which once-living (organic) organisms are decomposed.</span>
Sap is produced in the leaves as a result of the photosynthesis process, the phloem then brings it down through the tree, to give nutrients to the rest of the tree. It is tapped through the trunk, and taken from the phloem.
