1. Cellulose: This is the primary component of the cell wall, providing structural support and rigidity. It forms long, strong fibers that create a tough, protective layer around the cell.
2. Starch: While not a structural component, starch is a major storage polysaccharide in plants. It's made up of glucose monomers and is stored in granules within the chloroplasts and other plastids. Plants use starch as a readily available energy source.
