1. PROTISTS EUGLENA, AMOEBA, PARAMECIUM

2. WHAT IS A PROTIST? Kingdom Protista Very diverse single cell organisms. Eukaryotic Less complex with many different characteristics.

3. EUGLENA Single-celled Protist that live in fresh water. Captures and releases energy- producers (make their own food) and heterotrophs (gets food by eating other things) Some contain chlorophyll

4. MORE INFO ON EUGLENAS Eyespot helps them sense light. Can be autotrophic (produces their own food) Waste- Contractile Vacuole holds excess water and removes it from the cell. Movement- Flagella video

5. MORE INFO ON EUGLENAS Specialization - shape does change easily so it can move around Nucleus- controls activities of Euglena Cell Membrane- Outer Layer that allows movement in and out

6. AMOEBA Found in freshwater and salt water around a lot of dead and decaying material. Captures and releases energy- parasites, they get energy by invading other organsisms

7. MORE INFO ON AMOEBAS Waste- Contractile Vacuole holds excessive waste Movement- pseudopodia (false feet is used to engulf food) amoeba video

8. MORE INFO ON AMOEBAS Food Vacuole- part of cell that stores food

9. PARAMECIUM Found in freshwater. This is a single celled organism but is more complex than other organisms. Captures and releases energy- Cilia sweep food into food passageway. VIDEO

10. PARAMECIUM CONTINUED … Waste- Anal Pore (food waste is removed) and Contractile Vacuole (water waste) Movement- Cilia (tiny hairs that move back and forth.)

11. PARAMECIUM CONTINUED … Gullet- area where food is collected Oral Groove- Opening for taking in food Food Vacuole- food storage sac
