• Be aware of how they obtain food, reproduce, they
  are eukaryotic and examples.

5 Kingdom System(Bacteria? Monerans 6 Kindgom
System?Archaebacteria and Eubacteria)
3
3 Characteristics

• 1-Eukaryotic
• 2-Most unicellular (some multicellular)
• 3- Heterotrophic, autotrophic, and some act as
  decomposers

4
Plant-Like Protists

• CELL Uni/multicellular
• FOOD Autotrophic
• REPRO Asexual reproduction-no fusion of gametes
  offspring identical to parent
• MOVE flagella or cilia

5
A-Euglenas

• Unicellular
• Autotrophic
• Asexual
• Move with flagellum (in water)
• Contain chloroplasts and have an eye-spot

6
Euglena
7
B-Golden algae/Diatoms

• Unicellular cell wall
• Store food as oil
• Asexual
• Move with water movement
• When dead? shells used for glass, road paint
  reflection and toothpaste

8
Diatoms
9
C-Dinoflagellates

• Multicellular
• Autotrophic
• Asexual repro
• Flagellum for movement
• Can glow in the dark, food source, red tide

10
Dinoflagellates
11
Dinoflagellates

• May cause Red Tide

Toxic for both fish and people.

• ANIMAL-LIKE PROTISTS

17
2-Animal-Like Protists

• CELL Unicellular
• FOOD Heterotrophs
• REPRO Asexually reproduce
• MOVE Classificed by movement?Move with cilia or
  flagella

18
A-Ciliates

• Cilia
• Oral grooves to take in food
• Reproduce fission

19
Ciliates

• Paramecium (caudatum)

20
B-Flagellates

• Use flagellium
• What cell part will supply the energy for the
  flagellum?

21
Flagellates

• Trypanosoma (causes
• African Sleeping Sickness)
• Carried by the tse tse fly

22
C-Amoeboids

• Also called sarcodines
• Have pseudopods- false-feet to capture food
  (endocytosis)

23
Amoebas

• Moves with pseudopodia/false feet

24
Amoebas Their Relatives Foraminiferans
25
Amoebas Their RelativesRadiolarians
26
D-Sporozoa

• All parasites? feed on blood
• Move only by insects or animals

27
Sporozoans

• They cannot move on their own
• Plasmodium (vivax) is carried by mosquitoes

28

• PLANKTON
• AND FUNGUS-LIKE
• PROTISTS

29
3-Plankton/Fungus-like Protists

• CELL Multicellular
• FOOD Autotrophic
• grass of the sea? food!
• MOVE Most are not mobile (except by current)
• Produce lots of O2

Fungus-Like Protists

• Slime Molds
