The cell is the basic unit of life. This makes sense given that every part of our body is made up of them, but not all cells are the same. In fact, our bodies are made up of over 200 types of specialized cells. Being specialized means that even though they are similar, cells differ in size, shape, or function depending on their role in our bodies. In other words, each type of cell is modified to work in the way our bodies need it to.
