Cell Theory:
1. Every organism is composed of one or more cells.
2. The cell is the smallest unit that has the properties of life.
3. The continuity of life arises directly from the growth and division of single cells.

Eukaryotic Cells• have a nucleus• have organelles (compartments that enable a cell to
function and reproduce)
• Animal Cells• Fungi• Plants
