PROTISTS EUGLENA, AMOEBA, PARAMECIUM, VOLVOX

WHAT IS A PROTIST? • Kingdom Protista • Very diverse single cell organisms. • Eukaryotic • Less complex with many different characteristics.

EUGLENA • Single-celled Protist 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 • Eyespot helps them sense light. Can be autotrophic (produces their own food) • Waste- Contractile Vacuole holds excess water and removes it from the cell. • Movement- Flagella • video

MORE INFO ON EUGLENAS • Specialization shape does change easily so it can move around • Nucleus- controls activities of Euglena • Cell Membrane. Outer Layer that allows movement in and out

AMOEBA • Found in freshwater and salt water around a lot of dead and decaying material. • Captures and releases energyparasites, they get energy by invading other organsisms

MORE INFO ON AMOEBAS • Waste- Contractile Vacuole holds excessive waste • Movementpseudopodia (false feet is used to engulf food) • amoeba video

MORE INFO ON AMOEBAS • Food Vacuole- part of cell that stores food

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

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

PARAMECIUM CONTINUED… • Gullet- area where food is collected • Oral Groove. Opening for taking in food • Food Vacuole- food storage sac

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 energyphotosynthesis and flagella help bring in nutrients. • eyespots to help sense light.

VOLVOX CONTINUED… • Movement- Many flagella help move it. • Cytoplasm- gel like substance
