1. PROTISTS

2. YOU MUST KNOW… SOME DON’T CLASSIFY PROTISTS AS A KINGDOM
HOW CHLOROPLASTS AND MITOCHONDRIA EVOLVED THROUGH ENDOSYMBIOSIS

3. CONCEPT 28.1
MOST EUKARYOTES ARE SINGLE-CELLED ORGANISMS

4. PROTISTS ARE… EUKARYOTES THAT ARE NEITHER PLANTS, ANIMALS, NOR FUNGI
PROTISTS ARE PARAPHYLETIC – MANY ARE MORE CLOSELY RELATED TO PLANTS, FUNGI, OR ANIMALS THAN TO OTHER PROTISTS

5. PROTISTS
VARY IN STRUCTURE AND FUNCTION MORE THAN ANY OTHER GROUP OF EUKARYOTES
COMMONALITIES ARE:
MOST ARE UNICELLULAR
MOST USE AEROBIC METABOLISM AND HAVE MITOCHONDRIA

6. MITOCHONDRIA AND CHLOROPLASTS EVOLVED THROUGH ENDOSYMBIOSIS
THEY WERE ORIGINALLY UNICELLULAR ORGANISMS ENGULFED BY OTHER CELLS THAT ULTIMATELY BECAME ORGANELLES IN THE HOST CELLS

7. 3 CATEGORIES PLANT-LIKE PROTISTS – PHOTOSYNTHETIC
ANIMAL-LIKE PROTISTS – INGEST
FUNGUS-LIKE
PROTISTS –
ABSORB
