el A.) Cell theory :

1.) All organisms are made of cells.
2.) All existing cells are produced by other living thing.
3.) The cell is the most basic unit of life.

B.) Contributors to the Cell Theory:

People| Information|
Hooke| He was the first to identify cells and he also named them.| Leeuwenhoek| He made better lenses so he observed cells in greater detail.| Schledien| He was the first to note that plants are made of cells.| Schwann| He concluded that all living things are made of cells.| Virchow| He proposed that all cells come from other cells.| C.) Prokaryotic vs. Eukaryotic

* They can be single celled.

D.) Characteristics of all cells
