1. What does the cell theory state?- The cell theory states that a cell is the basic unit of life, and nothing smaller than a cell can live. All living things are made up of cells. New cells can arise only from preexisting cells. These are the three main poits that the theory states.

2. Why are cells so tiny?- Cells are so tiny, because of the surfacearea-to-volume ratio. Nutrients enter into a cell, and the waste product leaves at the surface. As a result the greater the amount of the surface, the greater the ability to get material in and out of the cell

3. How do Light Microscope and Electron Microscopes differ from one another?- Light Microscopes use a set of glass lenses and light rays passing through the object to magnify objects, and the image can be scene directly by the human eye. Electron Microscopes produce much higher magnifaction than a Light Microscope. They also have the ability to make out detail in enlarged images.
