Here's the breakdown:

* Cells are the basic building blocks of all living organisms. They are the smallest unit of life that can function independently.

* Organs are made up of different tissues that work together to perform a specific function. For example, the heart is an organ composed of muscle tissue, nervous tissue, and connective tissue.

Think of it like this:

* A cell is like a brick.

* A tissue is like a wall made of many bricks.

* An organ is like a house built from many walls.

So, organs are much larger and more complex than cells. They are made up of many cells organized into tissues.
