| Term | Definition |
|---|---|
The characteristic that all protists | All are eukaryotic in the kingdom |
Endosymbiotic Theory | --introduced by Lynn Margulis in the 1960s
--explains the evolution of the original eukaryotes from ancestral prokaryotes
--also explains the evolution of mitochondria and chloroplast in eukaryotic cells.
|
Grouping A. Flagellated Protists | all contain flagella for locomotion that evolved from a common ancestor |
what grouping is
--1. Phylum Diplomonadida
– 2. Phylum Parabasala
– 3. Phylum Kinetoplastida
– 4. Phylum Eugleno | A. Flagellated Protists |
Grouping B. Alveolates | All have membrane-bound sacs under the plasma membrane that regulate water and ion balance and stabilize the cell’s surface |
What grouping is:
1. Phylum Dinoflagellata
2. Phylum Apicomplexa
3. Phylum Ciliophora | B. Alveolates |
Alveoli | Are sacs under the plasma membrane are a defining characteristic of alveolates |
Grouping C. Stramenopiles | Protists with reproductive cells possessing two flagella - one “hairy” flagellum and one "smooth" one |
What grouping is:
1. Phylum Oomycota - water molds
2. Phylum Bacillariophyta - diatoms
3. Phylum Chrysophyta - golden algae
4. Phylum Phaeophyta - brown algae | C. Stramenopiles |
Stramenopile flagella | most stramenopiles, have reproductive cells with two flagella: one covered with fine stiff hairs and one smooth, |
Zoosporangia-- In Phylum Oomycota | are asexual reproductive structures that produce asexual zoospores. Each one has a smooth and a hairy flagellum in aquatic water molds. |
Oogonia- In Phylum Oomycota | are female sexual reproductive structures that produce
eggs in aquatic water molds. |
Antheridia- In Phylum Oomycota | are male sexual reproductive structures that produce sperm in aquatic water molds. |
Grouping D. Amoebozoans | use pseudopodia, cytoplasmic cellular projections for movement and feed by phagocytosis. |
what grouping is:
1. Phylum Gymnamoeba - free-living amoebas
2. Phylum Entamoeba - parasitic amoebas
3. Phylum Myxogastrida – plasmodial slime molds
4. Phylum Dictyostelida – cellular slime molds | D. Amoebozoans |
Phagocytosis | the engulfment of food into vesicles |
Grouping E. Phylum Rhodophyta | Is All Red Algae |
Grouping F. Phylum Chlorophyta | Is Green Algae
-closest living ancestor to plants |
