Kingdom Protista Flashcards
Polyphyletic
A group with many different ancestors, each with very different morphology, ecology, and genetics
4 Nutritional Strategies
1) Autotroph
2) Heterotroph
3) Mixotroph
4) Animal-like, plant-like, and fungi-like
Mixotroph
Combines autotrophic and heterotrophic strategies
Endosymbiosis
Early eukaryote took in other cells that became organelles
Primary Symbiosis 2 Types
1) Mitochondrion: Absorbed an aerobic prokaryote for cellular respiration
2) Chloroplast: Absorbed a cyanobacterium for photosynthesis
How many membranes do Mitochondria and Chloroplasts have through Primary Endosymbiosis?
They have 2 membranes.
Primary Symbiosis Examples
Red Algae (Dinoflagellata) and Green Algae (Euglenophyta)
Secondary Endosymbiosis
Absorbed an eukaryotic algal cell
Where does the Chloroplast get its 4 membranes from in Secondary Endosymbiosis?
2 from algal chloroplast; 1 from algal cell; 1 from phagocytosis
How does the Chloroplast end up with 3 membranes?
1 membrane is lost
Plant-like Protists
Phylum: Dinoflagellata
Domain, name meaning, and example?
-Dinoflagellates
“Whirling Whip”
Ex: Ceratium- Red Tide (Toxic Algae Bloom)
3 things Dinoflagellates Have
1) Reinforced Cellulose Plates
2) 2 flagella for swimming
3) Plastid from Red Algae
Plant-like Protists
Phylum: Euglenophyta
Domain, nutritional strategy, and environments
-Euglenids
Mixotrophic
Marine and Freshwater Environments
Euglena
2 things Euglenids have
1-2 flagella
Plastid from Green Algae
Plant-like Protists
Phylum: Bacillariophyta
Domain and Environment?
-Diatoms
Freshwater and Marine Phytoplankton
