Protists Domain: Eukarya Kingdom: Protista

Protists are: Single-celled (unicellular) or simple multicellular, microscopic, eukaryotic (with a nucleus) organisms

(Phytoflagellates): Autotrophs (self- nourished) Producers - produce their own food from light.

Algae Green Algae (7500sp) Red Algae (5000sp) Used in making ice cream Brown Algae (1500sp)

Euglena Flagellum Eyespot Chloroplasts Uses its eyespot to sense sunlight Moves by 2 flagella (1 short and 1 long) Contains chloroplasts to produce food for itself Eyespot Chloroplasts

Diatoms Colorful - Many Shapes Phytoplankton Used to make toothpaste, insecticides and dynamite

Dinoflagellates (whirling-whip) 2 Flagella; Cell Wall Red Tide

Heterotrophs (other-nourished) that MOVE Protozoans Protists that move, but cannot make their own food

Sarcodines Pseudopods -extensions of the cell membrane and cytoplasm Engulf food particles Assist with movement Amoeba Radiolarian

Ciliates Have small, hair-like projections called cilia on the outside of their bodies Provide movement Act as sensors Can help sweep in food Paramecium

Zooflagellates Protists that move using a flagellum Live in water or within other organisms Symbiotic relationship: Termites and wood roaches rely on a type of zooflagellate to digest the wood

Heterotrophs that can’t move Slime Molds – Cause of the great potato famine in Ireland; reproduce by spores Sporozoans – parasites that feed on cells and body fluids of their host animal Reproduce by producing spores
