  1. PROTISTSEUGLENA, AMOEBA, PARAMECIUM, VOLVOX

  2. What is a Protist? • An organism from the Kingdom Protista • Very diverse group of single-celled organisms. • Eukaryotic (they all have a nucleus) • Less complex than plants or animals

  3. Common ProtistsDraw Table below on Page 15

  4. EUGLENA • Single-celled Protists that live in fresh water. • Captures food by eating other organisms • Some contain chlorophyll

  5. More Info on Euglenas • Eyespot helps them sense light. • Waste- Contractile Vacuole holds excess water and removes it from the cell. • Movement- Flagella • video

  6. More Info on Euglenas • Reproduction- Asexual (binary fission) • Specialized Needs- shape does changes easily so it can move around • http://bio.rutgers.edu/euglena/

  7. AMOEBA • Found in freshwater and salt water around a lot of dead and decaying material. • Are parasites, they get energy by invading other organisims

  8. More Info on Amoebas • Waste- Contractile Vacuole holds excessive waste • Movement- pseudopodia (false feet) • amoeba video

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

  10. PARAMECIUM • Found in freshwater. This is a single celled organism but is more complex that other organisms. • Cilia sweep food into food passageway. • VIDEO

  11. Paramecium Continued… • Waste- Anal Pore (food waste is removed) and Contractile Vacuole (water waste) • Movement- Cilia (tiny hairs that move back and forth.)

  12. Paramecium Continued… • Reproduction- Sexual (two Parents) • Special features- Two nuclei (Macronucleus and Micronucleus)

  13. VOLVOX • Found in ponds ditches and puddles. • Composed of a colony of more than 50,000 tiny cells • Often times called algae.

  14. Volvox continued… • photosynthesis and flagella help bring in nutrients. • eyespots to help sense light.

  15. Volvox continued… • Movement- Many flagella help move the colony. • Reproduction- asexual and sexual, daughters colonies created.
