* Cells are the basic building blocks of all living organisms. They are the smallest unit of life that can function independently. They are enclosed by a membrane and contain genetic material (DNA).

* Tissues are groups of similar cells that work together to perform a specific function. Think of them as a "team" of cells.

Example:

* Muscle cells are individual cells that can contract.

* Muscle tissue is made up of many muscle cells working together to allow for movement.

In summary:

* Cells are individual units.

* Tissues are collections of cells with a shared purpose.

Think of it like this: a brick is a single cell, and a wall is a tissue made of many bricks.
