Verified step by step guidance

Understand the definition of polysaccharides: Polysaccharides are long chains of monosaccharide units linked by glycosidic bonds. They serve various functions in living organisms.

Identify the primary functions of polysaccharides: They are primarily involved in energy storage and structural support.

Differentiate between types of polysaccharides: For example, starch and glycogen are polysaccharides that store energy in plants and animals, respectively, while cellulose provides structural support in plant cell walls.

Evaluate the statement: The statement 'Polysaccharides are the macromolecules that act as a source of energy storage' is true because polysaccharides like starch and glycogen are indeed used for energy storage.

Conclude the analysis: The correct answer to the problem is 'True' because the statement accurately describes one of the primary functions of polysaccharides.
