What are the three statements of the cell theory?
1. All living organisms are made of one or more cells
2. Cells are the basic units of structure and function
3. Cells come from pre-existing cells

Why is a small surface area-to-volume ratio ideal for cells?
Quick exchange of materials in and out of the cell
