Sign up (free) to study this.
what were the first eukaryotic cells to evolve
protists
what are the types of protists
algae, fungus like, protozoan
what is known as the first animals, but arent really animals
protozoa
what are 4 characteristics of protozoa
single celled, complex, heterotrophic, diverse
what are the groups in protozoans (4)
zooflagellates, alveolates, amoeba, cercozoa
what are the groups of zooflagellates (3)
choanoflagellates, excavates, discicristates
what are the groups of alveolates (2)
ciliates, apicomplexan
what are the groups of cercozoa (2)
actinopods, foraminoferns
what are the groups of excavates (2)
giardi intestinalis, trychonymphs
what is the group of discicristates
trypanosomes
are zooflagellates unicellular of multicellular
unicellular
how do the zooflagellates move, like what structure do they use
flagella
what is the structure of the flagella of the zooflagellate
they have a eukaryotic structure (9+2)
wtf is a 9 + 2 structure
2 central microtubules and 9 double microtubules
are zooflagellates autotrophs or heterotrophs
heterotrophs
where do excavates live? why?
they live inside hosts because they are endosymbionts. they live in the part of the host with low oxygen
what is the word for low oxygen
anoxic
how do excavates get their energy
they have anaerobic pathways for fermentation, since they dont have mitochondria
where do the giardia intestinalis live
they live in the small intestine
what does the giardia intestinalis cause
it causes back packers diarreah
where do the trichonymphs go
they go to the gut of the termites
what relationship does the trichonymph hold?
they have a mutually beneficial relationship with bacteria, where the bacteria digests cellulose
what is a discicristate?
disc shaped mitochondral cristae
where do the trypanosome brucei live
in their host, because they are straight paraSITES!
how are the trypanosomes transmitted
tse tse flies carry them to the humans
what does a trypanosome cause (4)
african sleeping sickness, which causes nervous disorders, comas and death
what are choanoflagelletes? (2)
the are collared zooflagellates, and the common ancestor of all animals
what exactly IS a collared zooflaggelate
its one flagellum surrounded by microvilli
what structures does the ciliate have in it? (5)
pellicle, cilia, macronucleus, micronucleus, and some have trychocystsin
what is the pellicle made up of
alveoli
what is the pellicle like
flexible
where is the pellicle
on the outter part of the ciliate
what is cilia in relation to flagella
shorter and more numerous
what structure do the cilia have
9+2 structure
where are the cilia located
inside and through the pores of the pellicle
what are trichocysts?
organelles in the pellicle that become toxic filaments and capture the fude
what does the macronucleus do
control metabolism and growth
what does the micronucleus do
controls sexual reproduction
how do ciliates move
locomotion by cilia
what kind of reproduction do cilia do
as sexual and sexual- conjugation
what is conjugation in cilia
the exchange of micronuclei
where do ciliates live
some are parasites but most are free living
what class are the apicomplexans part of
sporozoans
what structure does the apicomplexan have
an apicomplex
what does the apicomplexan do?:
it has microtubules that attach the parasite to the host cell
how do apicomplexans move
flexing
how do apicomplexans eat
they eat the stuff that its host has
how do ciliates reproduce
asexually and sexually
where do apicomplexans live
they are parasitic
what is an example of an apicomplexan
plasmodium
what does plasmodium cause
malaria
where does the plasmodium find a host
red blood cells and liver
where are they found
tropics
how many people get infected every year and die
300 million infected, 1-3 die
who carries it
mosquitoes
what is the structure of cercozoa
they have a test and cytoplasmic projections that shine through
what is a test
the hard outer shell of cercozoa
what are the tests of foraminoferns like
calcium carbonate with small pores
how do forarminoferns get food
they have a strand of cytroplasm that catches the food
where are foraminoferns found
in marine habitats
what happens to foraminoferns
they die and form thick marine sediments, then they mash up and form land forms of chalk in dover england
what is the structure of an actinopod
they have pores in their shell, along with axopods, and radiolarian
what are axopods
thin projections of cytoplasm
what strengthns the axopods
microtubules
what is radiolarian
actinopods whose shells are glassy and made of silica
how do actinopods move
axopods
how do actinopods get food
axopods catch the prey and engulf it
where do actinopods live
with marine plankton
whats structure does amoebozoa have
pseudopodia
what are pseudopodia
temporary cytoplasmic projections
what is an example of an amoeboza
amoeba
are amoeba unicellular or multicellular
null
how do amoeba get around
the get around by lobose pseudopodia
what does lobose mean
rounded and wide
how do amoebozoa get food
their pseudopodia engulf food and the food vaculole fuses with the lysosome
what kind of reproduction do amoeba do
asexual
where do amoeba live
most are free living, but some are parasitic and opportunistic
what does a parasitic amoeba cause
entamoeba hystolytica cause a disease called amoebic dysentery. this casuees exploding/ fulminating diareeah
what does opportunistic amoeba cause and for who and how, and what is the thing called
in humans, naegleria fowleri gets into nose, then brain and kills the person in 3 days
where can you find naegleria fowleri
in warm waters like florida and texas
