PROTIST NOTES Mr. Peterson

Animal-like Protists n n From Bacteria to Plants (small book B) pages 37 B - 40 B. General Characteristics All are hetertrophs n Known as protozoans n Unicellular (one celled) n Classified by how they move n

Animal-like Protists n Ciliates Have cilia = short, threadlike structure n Example: Paramecium n

Animal-like Protists n Flagellates Move by using flagella n Some are parasites n Some for symbiotic relationship n

Animal-like Protists n Sarcodines Move with pseudopods (temp extensions of cytoplasm) n Also feed with pseudopods n

Animal-like Protists n Other protozoans n Parasites

Fungus-like Protists n n From Bacteria to Plants (small book B) pages 40 B – 42 B. General Characteristics Produces spores (like fungi) n Most move place to place using pseudopods n Heterotrophs n Have cell walls n

Fungus-like Protists n Slime Molds Feed on decaying logs/leaves in moist, cool, shady environments n Many different colors n

Fungus-like Protists n Water Molds and Downey Mildews Molds- mass of thread like/fuzzy, white growths (caused potato famine) n Mildews- live on above –ground parts of plants n

Plant-like Protists n n From Bacteria to Plants (small book B) pages 33 B – 36 B. General Characteristics Contain chlorophyll in chloroplasts = able to make own food (autotroph) n Known as algae n Unicellular OR Multicellular n

Plant-like Protists n Diatoms Glasslike boxes around them n Fresh and salt water n Unicellular n Used in toothpaste and polishes n

Plant-like Protists n Dinoflagellates Two flagella and unicellular n Salt water n Many glow n Cause red tides n

Plant-like Protists n Euglenoids Eyespot helps move toward light n Unicellular n Can change to be heterotroph n

Plant-like Protists n Red Algae Red colors absorb light n Multicellular seaweed n Live 200 M deep in ocean n In foods like ice cream n Carrageenan n Alginates n Beta Carotene n

Plant-like Protists n Green Algae Multicellular seaweed or Unicellular n Green color/pigment n Fresh water n

Plant-like Protists n Brown Algae Multicellular seaweed n Saltwater n Brown Pigement (Kelp) n Protists Brain Pop
