Here's why:

* Molecules are the building blocks of everything around us. They are made up of atoms bonded together. Think of water (H2O), sugar, or protein – these are all molecules.

* Cells are the basic unit of life. They are made up of many different molecules organized together to perform specific functions.

Think of it like this:

* A brick is like a molecule.

* A house is like a cell.

The house is made up of many bricks, just like a cell is made up of many molecules.
