Cell Theory

1. All living things are made of cells

2. Cells are the basic unit of structure and function in living things

3. All cells are made from other cells

2 major types of cells: 1. Prokaryotic cells: Super small & simple Do not have membrane bound organelles Do not have a nucleus Earliest type of cell Single-cell organisms EX: bacteria

2. Eukaryotic Cells: Larger, more complex Contain membrane bound organelles Have a nucleus Evolved later Single or multi-cell organisms EX: plants, animals, protists &fungi

ALL cells: Contain an outer membrane & cytoplasm Can reproduce themselves Contain genetic material
