* Cell theory states:

* All living things are made up of cells.

* Cells are the basic unit of life.

* All cells arise from pre-existing cells.

* Organelles are specialized structures within a cell that perform specific functions. They are essential for the cell to function, but they are not considered the fundamental unit of life themselves.

Think of it this way:

* A cell is like a house. It's a complete, self-contained unit capable of independent life.

* Organelles are like the rooms in the house. Each room has a specific purpose (kitchen, bedroom, bathroom), but they all work together to make the house function.

The cell is the fundamental unit of life, and organelles are the components that make that unit function.
