* Size: Cells are microscopic, but they are still vastly larger than molecules. A typical human cell is about 10-100 micrometers in diameter. Molecules, on the other hand, are measured in nanometers (a nanometer is one billionth of a meter). So, a cell is about 10,000 to 100,000 times larger than a typical molecule.
* Complexity: Cells are complex structures made up of many different types of molecules. They contain organelles, membranes, and genetic material, all of which are made up of smaller molecules. Molecules are the basic building blocks of cells.
Analogy: Imagine a city (the cell) made up of many buildings (organelles). Each building is made of bricks (molecules). The city is much bigger than a single brick, just as a cell is much bigger than a single molecule.
