Verified step by step guidance

Understand the role of polysaccharides in biological systems. Polysaccharides are long chains of monosaccharides linked by glycosidic bonds, and they serve various functions such as energy storage and structural support.

Identify the common polysaccharides and their functions. Starch, glycogen, chitin, and cellulose are all polysaccharides, but they have different roles in organisms.

Recognize that starch is the primary storage polysaccharide in plants. It is composed of amylose and amylopectin, which are glucose polymers, and is used by plants to store energy.

Differentiate starch from other polysaccharides. Glycogen is the storage polysaccharide in animals, chitin is used for structural purposes in fungi and arthropods, and cellulose provides structural support in plant cell walls.

Conclude that starch is the correct answer for the polysaccharide primarily used by plants to store excess monosaccharides, based on its function and composition.
