4. Autotrophic or Heterotrophic (Ingestion, or Absorption)
B. Three Groups
1. Protazoa- Animal like protists (Ingestion heterotrophs)
2. Algae- Plant-like (Photosynthetic autotrophs)
3. Psuedo Fungi- Heterotrophic (Absorption)
C. Protozoans
-Marine, fresh water and moist
-Unicellular, heterotrophs, usually Asexual
1. Amoeba- No cell wall
A. Psuedopodia- extensions of the plasma membrane filled either, cytoplasm, freshh water, or salt water
- Diffusion- centralized vacoule
2. Flagellates
-Phylum Zoamastigina
-One or more Flagella
-Termite gut symbiont
-African sleeping sickness (tse-tse fly)
3. Cilliates- Phylum Ciliophora (Includes Paramecuims)
-Aquatic habitats, Asexuall, and have a form of
conjugation
-Cilia, oralgroove, gullet, anal pore
-Micronucleus and Macronucleus
-Contractile Vacoule
4. Sporozoans- Phylum Sporozoa
- produce a spore reproductive cell which develops into a mature organism
- All parasites
1. Malaria- Plasmoduim
D. Algae
-Photosynthetic autotrophs
-Many different pigments
-Phytoplankton- photosynthetic plankton
3. Dinoflagellates
-Phylum Dinoflagellata
-2 flagella
-Cell walls made of cellulose
-Chlorophyl and caretenoids give it a red pigment
-Red Tide is caused by this algae
4. Red Algae
-Phylum Rhodophyta
-Red pigments
-Multicellular "seaweed"
5. Brown Algae
-Phylum Phaeophyta
-Fucaranthia pigment
-Kelp 60m long
6. Green Algae- 7,000 species
-Phylum Chlorophyta
-Unicellular, multicellular, or colonial
-Food products
-Sexual and Asexual
-Gave rise to the first land dwelling plants
E. Fungus like protists
-Plasmodial slime
-Molds and cellular slime molds
-Watermolds (downy mildew)
-Potato blight of 1840
