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

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

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.

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
