1 p. 468 Protist Notes

2 Protists Eukaryotes (have nucleus)
Most unicellular (made of only 1 cell) Many kinds

3 I. Animal-Like Protists (Protozoans)
Heterotrophs (can’t make own food) Most able to move around Unicellular Types:

4 Protozoan with Pseudopods (Sarcodines)
Pseudopod – “false foot” or bulge of cytoplasm used to move/feed Example: Amoeba

5 2. Protozoans with Cilia (Ciliates)
Cilia – hairlike projections that move like waves, used to move or get food Example: Paramecium

6 3. Protozoans with flagella (flagellates)
Flagella – long, whiplike “tail” Symbiosis – relationship where at least one partner benefits Mutualism – relationship when both partners benefit Parasite – relationship when one partner harms another (its host)

7 4. Protozoans that are parasites
Feed on the cells/body fluids of their host

8 II. Plantlike Protists Autotrophs (make own food using sun’s energy)
Algae Important food source Contribute oxygen Many pigments (chemicals that produce color)

9 1. Diatoms Unicellular Dead used as Polish Scouring insecticide

10 2. Dinoflagellates Unicellular 2 flagella Some glow in dark

11 3. Euglenoids Green Heterotrophs when no sun Example: Euglena

12 4. Volvox Volvox are round They live in colonies autotrophic

13 5. Green Algae Most unicellular Found in water or land

14 6. Brown Algae Most seaweeds Color: green, yellow, orange, or brown
Live in water Some used as food

15 1. Slime molds Bright colors Vary in size Ooze

16 2. Water mold/downy mildew
Live in water/moist places Example: water mold that killed Irish potato crops (1845, 1846)
