The cell theory tells us that the cell is the basic unit of life, all organisms are made up of cells, and new cells come only from other living cells. Whether you are a simple organism, an amoeba, made up of only one cell or a complex organism, a human, made up of many cells, each cell is built the same way. A single cell works like a fast food restaurant. There are many important jobs to be done to get an order out to the customer, someone to make the french fries, someone to cook the hamburgers, someone to prepare the sandwiches, someone to prepare the drinks, someone to take the order, etc. In order for a cell to work as efficiently, there are many cell parts that must work together as well.
Cells can also work together to perform some complicated functions.
For example, cells work together to form muscle tissue which aids in movement. In later chapters, we will be investigating the detailed work of the cell as they function together in all of the systems of the human body. However, before we can understand these complicated functions we must understand the functions of the cell and it's parts. Draw and cut a picture of your cell part for both the plant and animal cell. If the cell is equipped with more than one of your cell parts, then you need to draw and cut out the appropriate number of cell parts for each cell.
