Here's a breakdown:

* Carbohydrates are a large group of organic compounds that include sugars, starches, and cellulose.

* Monosaccharides are the simplest form of carbohydrates. They cannot be broken down into simpler sugars.

* Examples of common monosaccharides include glucose, fructose, and galactose.

Think of it this way: Monosaccharides are the building blocks of larger carbohydrates, just like bricks are the building blocks of a house.
