1. Prokaryotic Cells
They do not have a membrane bound nucleus and lack organelles. They are generally much smaller than a eukaryotic cell. Three general shapes: rod shaped, spherical and spiral. Has circular chromosomes.

2. Eukaryotic Cells
Contain membrane bound organelles that perform specific metabolic functions. Depend on oxygen for their metabolism.

3. Microscopic organisms
Many eukaryotic and prokaryotic cells are living along side us and we are not even aware of them.
Bacteria
Amoeba
Paramecium
Ciliates
Euglena

4. Squish the amoeba
Single celled organisms that live in lakes and ponds and sometimes inside other organisms.
Distinguishing feature:
PSEUDOPOD – used to move around and eat with.

5. Pod the amoeba
Amoeba’s come in many different shapes and sizes

6. Peggy the paramecium
Paramecium have a continuous covering of cilia that allows them to move around quickly.

7. Principal planaria
Flat worm, those are not eyes, they are actually light spots.

8. Endocytosis – cell eating

9. Slime mold
A quick moving and multiplying protista, uses spores to reproduce, a primitive form of reproduction. Can grow to be as large as a large pizza on the forest floor.
