Here's a breakdown:

* Monosaccharides: These are simple sugars, like glucose and fructose.

* Disaccharides: These are formed when two monosaccharides bond together, like sucrose (glucose + fructose).

* Polysaccharides: These are complex carbohydrates formed by the bonding of many monosaccharides.

Examples of polysaccharides include:

* Starch: A storage polysaccharide in plants, made of many glucose molecules.

* Glycogen: A storage polysaccharide in animals, also made of many glucose molecules.

* Cellulose: A structural polysaccharide in plants, also made of many glucose molecules, but arranged differently than starch or glycogen.
