6. Today’s Objective
SWBAT differentiate between prokaryotic and eukaryotic cells SWBAT give examples of prokaryotic and eukaryotic organisms

7. The Two Types of Cells
As microscopes got more powerful, scientists started look at the parts inside cells.
An organelle is a small, specialized structure inside a cell.

8. The Two Types of Cells All cells can be divided into two categories:
Pro= before
Prokaryotic cells came BEFORE eukaryotic cells
Eukaryotic Cells
Prokaryotic Cells

9. Prokaryotic cells (bacteria only)
(Dots)

10. Prokaryotic Cells All bacteria are always unicellular such as E. coli
Do NOT have (lacks) a nucleus or any other large organelles.
DNA floats around in the cytoplasm
Pro= Before. Existed before the nucleus.
Much smaller and simpler than eukaryotic cells.

11. Eukaryotic cells (every other organism)

12. Think: Why is this important????
Eukaryotic cells
Eu- = TRUE. They have a true nucleus
The nucleus contains DNA and therefore controls the cell.
Found in all animals, plants, and fungi as well as unicellular algae and protists such as an Amoeba.
Contain membrane-bound organelles, which allow different parts of the cell to do different functions.
