Here's a breakdown:

* Monosaccharides: These are the simplest form of carbohydrates and are the building blocks for larger carbohydrates. Examples include glucose, fructose, and galactose.

* Disaccharides: These are formed when two monosaccharides join together. Examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).

* Polysaccharides: These are complex carbohydrates formed by long chains of monosaccharides. Examples include starch, glycogen, and cellulose.

So, to summarize: monosaccharides are the monomers that make up all larger carbohydrates.
