What is the difference between a cell and an organism?

A Cell is the smallest thing that can truly be considered alive. "Organism" just means one body, one living thing. You are an organism. A tree is an organism. A bacterium is an organism. Some organisms are made up of many cells, like you and I, whereas some organisms are only a single cell, like bacteria or amoeba.
