PROTISTS EUGLENA, AMOEBA, PARAMECIUM, VOLVOX
What is a Protist? Kingdom Protista Very diverse single-celled organisms. Eukaryotic Less complex with many different characteristics.
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
More Info on Euglenas Reproduction- Asexual (binary fission) Specialized Needs- shape does changes easily so it can move around http://bio.rutgers.edu/euglena/
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
More Info on Amoebas Feedback- pseudopodia (false feet) Waste- Contractile Vacuole holds excessive waste Movement- pseudopodia (false feet) amoeba video
More Info on Amoebas Reproduction- Asexual (binary fission) Specialized Needs- n/a
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
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.)
Paramecium Continued… Reproduction- Sexual (two Parents) Specialized Needs- Specialized Function: Two nucleuses (Macronucleus and Micronucleus)
VOLVOX Found in ponds ditches and puddles. Composed of a colony of tiny flagellate cells. (more than 50,000 cells) Often times called algae.
Volvox continued… Captures and releases energy- photosynthesis and flagella help bring in nutrients. Feedback- eyespots to help sense light. Waste- n/a
Volvox continued… Movement- Many flagella help move it. Reproduction- asexual and sexual, daughters colonies created. Specialized needs- n/a
