1. Kingdom Protista Most UNICELLULAR, some MULTICELLULAR EUKARYOTIC
3 groups based on nutrition:
Protozoans (animal-like, heterotrophs)
Algae (plant-like, autotrophs)
Slime Molds (fungus-like, decomposers)
**Eukaryotes that don’t belong to Kingdoms Fungi, Plantae or Animalia

2. ENDOSYMBIONT HYPOTHESIS
So where did Eukaryotic cells come from?
One theory states that a variety of prokaryotic cells formed symbiotic relationships between each other and then, gathered into one another.

3. - One specific organism called Cyanophora paradoxa
- One specific organism called Cyanophora paradoxa. It is a eukaryotic plant-like protist, but inside its cell it possesses blue-green bacteria growing inside of it instead of chloroplast organelles.

4. Protozoans (Animal-like)
“PROTOZOA” = First Animal
classified primarily by their means of locomotion.
PHYLUM CILIOPHORA – Ciliates
Have CILIA – which they use to move & feed
Mostly freshwater
Ex) Paramecium

5. 2. PHYLUM SARCODINA SARCODE = Is Greek for JELLY
move & eat using “PSEUDOPODS” = False Foot
Ex) Amoeba
Amoebic Dysentery

6. 3. PHYLUM ZOOMASTIGINA use one or more flagella to move around
“ZOO” means animal & most animals have a tail
TRYCHONYMPHA = Inside Termite Gut
GIARDIA = “Beaver Fever” Gastrointestinal Disease
TRYPANASOMA = African Sleeping Sickness

7. 4. PHYLUM SPOROZOA NO ability to move Most are parasitic
create SPORES that travel through bodily fluids & water.
Plasmodium Vivax = Malaria

8. The World Health Organization (WHO), in its latest estimate of malaria mortality, has concluded that around 881,000 people died from the disease in Around 91% of those who died were children in Africa. There were an estimated 247 million cases globally (range: 189–327 million).

9. Algae (Plant-Like) Photosynthetic (have chlorophyll)
PHYTA = PLANT
Photosynthetic (have chlorophyll)
Lacks conductive tissue = NON-VASCULAR
NO true roots
NO supportive stems
NO true leaves

10. Habitat: mainly aquatic some moist terrestrial species
Advantages of living in water:
Prevents drying out
Gives structural support
Provides nutrition
Helps to disperse spores & meeting of gametes

11. Roles in the environment:
Major food source for heterotrophs
Major producer of oxygen
Major component in plankton
Biofuel

12. EUGLENA (Phylum Euglenophyta)
Unicellular
No cell wall
Have pellicle
Use flagella to move
Ex) Euglena

13. 2. Fire Algae (phylum Pyrrophyta)
PYRRO = FIRE
Dinoflagellates
Unicellular
2 flagella spin the cells through water
Mostly marine (plankton)
Some bioluminescent
Ex) Gonyaulax – causes red tide

14. 3. Golden Algae (phylum Chrysophyta)
CHRYSO = GOLDEN
Diatoms
Unicellular; some colonial
No movement
Have glasslike cell walls containing silica

15. 4. Green Algae (phylum Chlorophyta)
Unicellular (phytoplankton) or multicellular
Most live in freshwater; some in shallow ocean floor
Some have symbiotic relationship with fungi (= lichen)
Ex) Volvox - colonial
CHLORO = GREEN

16. 5. RED ALGAE (phylum Rhodophyta)
Not all red
Mainly live in warm saltwater
Can use light that penetrates deep water
6. BROWN ALGAE (phylum Phaeophyta)
Cool, saltwater
Ex) Giant kelps

17. Slime Molds (Fungus-Like)
Most small
3 groups
Plasmoidal Slime Molds
Cellular Slime Molds
Water Molds
Commonly called “DOG VOMIT Slime Mold”

18. A million people are said to have died of hunger in Ireland in the late 1840s due to mass starvation. Cause: a water mold
