1. PROTISTS EUGLENA, AMOEBA, PARAMECIUM, VOLVOX

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

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.

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

12. VOLVOX Found in ponds, ditches, and puddles.
Composed of a colony of tiny flagellate cells. (more than 50,000 cells)
Often times called algae.

13. Volvox continued…
Captures and releases energy- photosynthesis and flagella help bring in nutrients.
eyespots to help sense light.

14. Volvox continued… Movement- Many flagella help move it.
Cytoplasm- gel like substance
