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

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

Heterotrophs (other-nourished) that MOVE
ProtozoansProtists 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

Example: Plasmodium -causes malaria, is transmitted
by mosquitos
