1. PROTISTS EUGLENA, AMOEBA, PARAMECIUM, VOLVOX

2. What is a Protist? Kingdom Protista
Very diverse single-celled organisms.
Eukaryotic
Less complex with many different characteristics.

3. EUGLENA Single-celled Protists 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 Feedback- Eyespot helps them sense light.
Waste- Contractile Vacuole holds excess water and removes it from the cell.
Movement- Flagella

5. More Info on Euglenas Reproduction- Asexual (binary fission)
Specialized Needs- shape does changes easily so it can move around

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 Feedback- pseudopodia (false feet)
Waste- Contractile Vacuole holds excessive waste
Movement- pseudopodia (false feet)
amoeba video

8. More Info on Amoebas Reproduction- Asexual (binary fission)
Specialized Needs- n/a

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

10. Paramecium Continued…
Feedback- n/a
Waste- Anal Pore (food waste is removed) and Contractile Vacuole (water waste)
Movement- Cilia (tiny hairs that move back and forth.)

11. Paramecium Continued…
Reproduction- Sexual (two Parents)
Specialized Needs- Specialized Function: Two nucleuses (Macronucleus and Micronucleus)

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.
Feedback- eyespots to help sense light.
Waste- n/a

14. Volvox continued… Movement- Many flagella help move it.
Reproduction- asexual and sexual, daughters colonies created.
Specialized needs- n/a
