  1. PROTISTSEUGLENA, 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 • video

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

  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. • VIDEO

  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

  15. Volvox Videos • video 1 • video 2 • video 3
