Classification
Based on the way they obtain nutrients

Produce much of earth’s O2
Have chlorophyll
(no roots, stems, leaves)
Multicellular and Unicellular

7. Plant-like Protists
Giant Kelp and Algae

8. Fungus-like Protists Heterotrophic Decomposer External Digestion

9. Importance Plant-like – Oxygen Fungus-like – Recycle (Trichonympha)
Symbiotic Relationships
Food Source
Phytoplankton/Zooplankton
Human use of algae
Produce 70% of Earth’s O2
Fungus-like protists recycle nutrients
Symbiotic relationships – ex: TRICK-OH-NIM-FAH live inside termintes to help digest wood
