Protists
Excavata
Parabasalids
reduced mitochondria
hydrogenosomes
reduced mitochondria hydrogen by-product
EX: Trichonomonas vaginalis
Eugelenozoans
Kinetoplastids
single large mitochondrion
kinetoplast
organized mass DNA
feed on prokaryotes aquatic/terrestrial
parasites
Ex: Trypanosoma=sleeping sickness
Eugelenids
pocket end cell
1/2 flagella
mixotrops
hetertrophs:phagocytosis
Diplomonads
reduced mitochondria
mitosomes
EX: Griardia intestinalis
groove on side cell body
SAR
Alveolates
Dinoflagellates
cellulose plates
2 flagella
"red tide" in Australia
carotenoid pigments in plastids
Apicomplexans
parasites of animals
sporozites
tiny cell
infectious
spread in host
Apical complex
end of cell
organelles
penetrate host
Plasmodium=maria
Cilliates
motile
with cilia
micro and macronuclei
Paramecium
Rhizarians
Forams
porous shells=tests
foram fossils
Radiolarians
delicate skeletons,silica
symmetrical
pseudopods radiate from center
Cercozoans
amoeboids
flagellated
heterotrophs/parasites
predators to bacteria
Stramenopiles
Golden Algae
yellow/brown carotenoids
bilflagellated
ALL photosynthetic
some mixotrops
freshwater/marine plankton communities
Ex:Dinobryon=colonial freshwater
Brown Algae
carotenoid
Ex: "seaweeds"
Diatoms
photosynthetic
affects global CO2
sink CO2 ocean floor
silicone dioxide=glass wall
most abundant photosynthetic organisms
lakes
oceans
diatomaceous earth
2 flagella
hair and non hairy
ARCHEAPLASTIDA

Green Algae
photosynthetic
charophytes
closely related to plants
chlorophytes
