23.3 - Groups of Protists Flashcards
Eukaryotic Supergroups
Excatavata subgroup names + examples
Diplomonads
Parabasalids
Euglenozoans (EXAMPLE: Euglena with eye spot)
The 6 Eukaryotic Supergroups
- Excavata
- Chromalveolata
- Rhizaria
- Archaeplastida
- Ameoebozoa
- Opisthokonta
Excavata (description)
Single-celled
Asymmetrical
Feeding groove “excavated” from one side
Two or more flagella
Often lack mitochondria
Example Excavata:
- Trychonympha spp, in termite guts digest cellulose
Chromalveolata (description)
Single-celled & Multicellular
Mostly photosynthetic
cell walls with cellulose
contains chlorophyll c
Chromalveolata subgroup names
- Dinoflagellates
- Apicomplexians
- Ciliates
- Diatons
- Golden algea
- Brown algea
- Oomycytes
CHROMALVEOLATA
Dinoflagellates
Single-celled
Photosynthetic, mixotrophic & heterotrophic
Posess flagellum
sometimes Bioluminescence
examples: red tide & shellfish poisoning
coral reef
CHROMALVEOLATA
Apicomplexians
Single-celled
Obligatory parasitic endosymbionts of animals
Posess an apicoplast which allows them to penetrate the host cell
CHROMALVEOLATA
Ciliates
Single-celled
Hair like appendiges used in swimming, feeding, etc.
Example: PARAMECIUM
CHROMALVEOLATA
Diatoms
Silicone shell / pretty arrangements / glassy
Single-celled
Photosynthetic
some use “Raphe” slit to move
CHROMALVEOLATA
Golden algea
Brown and yellow carotenoids
Biflagellated cells
Mostly unicellular, some are colonial
Freshwater species
CHROMALVEOLATA
Brown algea
Large
Marine
Cold areas
Example: GIANT KELP
CHROMALVEOLATA
Oomycetes
Fungus-like protists
Decomposers & Pathogens
Example: Potato blight disease & water mold
Rhizaria subgroup names
Cercozoans
Forams
Radioliarians
Rhizaria (description)
Single-celled amoeboids
Heterotrophic
Often produce shells or skeletons
Posess pseudopods (temporary arm projection)
