Protists Flashcards
ESAU
What are the 4 major groups
Excavata, SAR clade, Archaeplastida, Unikonta
Excavata - Diplomonads and Parabasalids
anaerobic or aerobic
Non-flagellated or flagellated
Anaerobic and flagellated
Excavata - Euglenozoan
What is their distinguishing feature
What are the 2 main groups with 1 example
Spiral/Crytaline rod inside of their flagella
Euglenids and Kinetoplastids - Trypanosomiasis
What are the 2 main groups of Unikonts
Amoebozoans
Opisthokonts
What are the 3 main groups of Archaeplastids - give 1 example for each
Red algae - Nori
Green algae - Sea lettuce
Land plants - Grass
How did land plants evolve from charophytes and what was the main stumbling block
Charophytes developed auxin
Photo-oxidative damage
SAR - What are the 3 major groups of the Stramenopiles
Diatoms, Golden algae and Brown algae
Why are diatoms important in ecosystems
They are the most abundant photosynthetic organisms in water and generate most of the organic matter for food
What is toxic about golden algae
Toxin prymnesin is produced that kills other algae, bacteria and fish
How is brown algae useful
Primary producers that provide habitats and nutrition on rocky shores
SAR - Alveolates - How are dinoflagellates useful
Symbiosis with corals and algae
SAR - Alveolates - What is a major species of parisitic apicocomplexans
Plasmodium
What is the importance of Forams in terms of environmental conditions
The chemical make-up of their shells are determined by environmental conditions so their fossils can infer past climatic conditions
Give one characteristic of each Rhizarian - Forams, Cercozoans and Radiolarans
F - Porous shell called tests
C - Flagellated
R - feed via phagocytosis
