General Characteristics and Animal Like Protists

2. General Characteristics
Eukaryotes
Difficult to classify
Classified into protists by what they are NOT
Eukaryotes that are NOT members of Kingdom Plantae, Animalia or Fungi
Mostly unicellular, but not all

3. Classification Classified according to how they get nutrition
Heterotrophs
Animal like protists
Photoautotrophs
Plant like protists
External digestion
Fungus like protists

4. Animal Like Protists 4 phyla according to movement Zoomastigina
Move with flagella
Absorb food through cell membrane
Ex. Giardia

5. Animal like Protists Sarcodina Move by pseudopods
Called amoeboid movement (‘ooozy’ critters)
Surround food, producing food vacuole
Ex. Amoeba proteus

7. Animal Like Protists Move with cilia
Food swept into gullet via cilia; food vacuole forms at base of gullet
Waste emptied via anal pore
Some have trichocysts
Defense projections (like a mini porcupine)

8. Ciliophora continued Macronucleus Micronucleus Contractile vacuoles
Working genetic material
Micronucleus
Extra copy of DNa
Exchange of micronuclei during conjugation increases genetic diversity
Contractile vacuoles
Gets rid of excess water 
Ex. Paramecium

10. Animal Like Protists Sporozoa Parasites Often have more than one host
Often have more than one host
Ex. Plasmodium

11. Diseases Caused by Animal Like Protists
Plasmodium: sporozoan causes Malaria
Trypanosome: zooflagellate causing African Sleeping Sickness
Entameoba: sarcodine causing amoebic dysentery (major killer in third world countries)
Giardia: zooflagellate causing intestinal disease in humans (present in Canada)
Paramecium coli: ciliate causing intestinal disease in humans (rare in Canada)

12. Ecology
Form symbiotic relationships (both organisms benefit) Ex. Termite
Decomposers
Food for other organisms
