5. Unifying Characteristics
Eukaryotic – cell with nucleus
Can be unicellular, multi-cellular, colonial
Can be heterotrophic, autotrophic, or saprotrophic
Can be motile or stationary
Used as a bio-indicator or healthy environments

6. Animal-like Protista Plant-like Protista Fungi-like Protista Motile
Heterotrophic
Use cilia, flagella, or pseudopodia to move
Known as protozoa
Stationary
Have chlorophyll as pigment for photosynthesis
Have chloroplasts
Autotrophic
Micro or macroalgae
Water molds or slime molds
Unicellular molds
Release enzymes out to environment to digest food (absorb nutrients)

7. Animal-like Protista HETEROTROPHIC
Use cilia, flagella, or pseudopodia to move
Engulf (eat) food
Micro-organisms
Can be parasitic

8. Protista Parasite Trypanisomastigote (animal-like protista)
African Sleeping Sickness – from the Tsete Fly

9. Malaria
Parasitic Protista

10. Malaria

11. Micro Plant-like Protista AUTOTROPHIC PHOTOSYNTHESIZE
Photosynthetic (autotrophic)
Stationary
In ponds and lakes
Delicate balance needed as can destroy water ecosystems if eutrophication occurs (over population, which damages aquatic life)

12. Macro Plant-like Protista AUTOTROPHIC PHOTOSYNTHESIZE
Macro-algae has recently been moved from Kingdom Plantae to Kingdom Protista
Use a range of pigments for photosynthesis (red, green, brown)
Make most of the atmosphere’s oxygen

13. Macro Plant-like Protista AUTOTROPHIC PHOTOSYNTHESIZE
Important food source for humans and create the “forests” of the oceans for marine life

14. Fungi-like Protista Decomposers
Water-molds and slime molds
Exo-enzymes for external digestion
Although unicellular, cells can swarm to look like a larger multicellular organism
Can create spores to survive harsh conditions
