Protists Flashcards
Diplomonida
clade 1-protist lack plastids and mitochondria do not have DNA, live anaerobic environments. 2 nuclei + multiple flagella
parabasala
clad 1-protist lack plastids and mitochondria do not have DNA, live anaerobic environments.
euglenozoa
clade 2-presence of crystalline rod inside flagella+have disk shaped mitochondrial christae
kinetoplastid
euglenozoa with single large kinetoplast mass of DNA in mitochondria.
euglenids
euglenozoa- lack cell wall but have pellicle. have light detector and short flagella
alveolates
clade 3-membrane bounded sacs (alveoli) beneath plasma membrane
dinoflagellates
alveolate - hamburger shaped with internal plates of cellulose with flagella in groove causes spinning. cause of red tide and bioluminescence
apicocomplexans
alveolate- parasites of animals by sporozoites. have nonphotosynthetic plastid: apicoplast.
plasmodium life cycle
apicocomplexan causes malaria; short dipolid zygote stage. oocyst produces sporozoites and gametocytes form in red blood cells
ciliates
alveolate- use cilia to move and feed
paramecium cycle
ciliate which produces 4 macronucleus and dipolid micronucleus during fusion
conjugation
two ciliates exchange haploid micronuclei
ciliates
apicocomplexan; most notable is paramecium
stramenophile
clade 4-smooth and hairy flagellum
oomycetes
stramenophile; water molds with cell walls made of cellulose and hyphae but are not fungi
diatoms
stramenophile; unicellular algae that have glass like wall with shoe box and lid with high forcegreat diversity
golden algae
chrysophytes, biflagellate and mostly unicellular
brown algae
mostly multicellular and also seaweed body called thallus that is plant like
cercozoans
class of amoebas with threadlike pseudopodia
forams
cercozoan- foram tests (shells) multichambered hardened with calcium carbonate
radiolarians
similar to cercozoan- tests made of silica; pseudopodia are axopodia that radiate
amoebozoa
lobe shaped pseudopodia; gymnamoebas, entamoebas, slime molds
gymnamoebas
unicellular free living heterotroph protists feeding on bacteria and other protists in soil and water
entamoebas
parasites that infect all classes of vertebrates and some invertebrates
slime molds
protist that produce fruiting bodies that aid in spore dispersal
plasmodial slime mold
mass called a plasmodium that is a single mass of cytoplasm undivided by membranes and contains many diploid nuclei
cellular slime mold
haploid; feeding stage single cell; asexual fruiting bodies;
red algae
close algal relatives; phycoerythrin; multicellular; alternation of generations; no flagellated stages in life cycle
green algae
chlorphytes and charophycaens; some of the algae that combines with fungi for lichens
vovlox
chlorophyte that is colonies of individual cells
ulva
chlorophyte that is truly multicellular
charophyceans
most closely related to land plants
