polysaccharides are used mainly as to store energy whereas monosaccharides are used to be used for respiration


polysaccharides (glycogen, starch and cellulose) are polymer of monosaccharides.

Glycogen is the storage molecule in animals. They have 1-4 glycosidic bond as well as the 1-6 glycosidic bond. It is insoluble so it is not affected by the water potential.

starch is the storage molecule in animals. They are actually made up of 2 compounds: amylose and amylopectin. Amylose has 1-4 glycosidic bond so it will spiral and amylopectin was more 1-6 glycosidic bonds meaning more glucose can be joined to form compact molecule.

Cellulose is more of a structural carbohydrates as they help strength the cell wall of a plant

Hope this helps x
