Term
What are the two major prokaryotic groups?
Definition
Archaebacteria, Eubacteria
Term
Three major groups of Archaebacteria:
Definition
Extreme thermophiles, extreme halophiles, methanogens
Term
Extreme thermophiles: respiration type
Definition
strict anaerobe
Term
methanogen respiration type
Definition
strict anaerobe
Term
extreme halophile respiration type
Definition
aerobic
Term
extreme thermophile: last electron acceptor
Definition
sulfur
Term
exterem halophile: how do they make their atp?
Definition
anaerobic eletron transfer
Term
extreme thermophiles are tolerant of:
Definition
heat
Term
extreme halophiles: ATP
Definition
aerobic, but can switch to photosynthesis.
Term
what do methanogens do?
Definition
produce methane
Term
extreme halophiles are tolerant of:
Definition
salt
Term
example of an extreme thermophile and where it is found:
Definition
sulflobus, hotsprings
Term
example of a methanogen and where it is found:
Definition
methananosarcina, cow intestines
Term
example of an extreme halophile and where it is found:
Definition
halobacterium, salt ponds
Term
How are Eubacteria categorized into groups?
Definition
based on their modes of nutrition
Term
three major groups of Eubacteria
Definition
photoautotrophs, chemoautotrophs, chemoheterotrophs.
Term
where do photoautotrophs get their nutrients?
Definition
they are self feeders
Term
where do chemoautotrophs get their nutrients?
Definition
self feeder
Term
where do chemoautotrophs get their nutrients?
Definition
not a self-feeder
Term
do photoautotrophic eubacteria have chloroplasts?
Definition
no, photosynthetic machinery embedded in their plasma membrane.
Term
example of a photoautotrophic eubacteria?
Definition
cyanobacteria
Term
what is the electron donor for chemoautotrophic eubacteria?
Definition
ammonia
Term
what is the global importance of chemoautotrophic eubacteria?
Definition
influences global cycling of nitrogen
Term
what are two types of chemoheterotrophs?
Definition
parasite and saprobes
Term
what is a parasite?
Definition
gets its nutrients from a living host
Term
what is a saprobe?
Definition
gets its nutrients from a dead host
Term
three examples of chemoheterotrophic eubacteria that are pathogenic bacteria?
Definition
E. coli, clostridium botulium, C. tetani
Term
what are the two viral multiplication cycles?
Definition
lysogenic and lytic
Term
lysogenic pathway
Definition
lysogenic pathway involves inserting viral dna into the bacterial dna, when the cell divides, it also copies the viral DNA. The cell then enters the lytic pathway
Term
lytic pathway
Definition
the virus inserts its genetic material into the cytoplasm, which directs the host cell to produce viral machinery. when the host cell becomes full of viruses, its lyses and releases them.
Term
Name all the phylum in kingsom protista: (9)
Definition
Euglenophyta, sarcodina, phyrrhophyta, chrysophyta, phaeophyta, chlorophyta, rhodophyta, apicomplexa, mastigophora
Term
what is the difference between a euglenoid and a non-euglenoid flagellated protozoan?
Definition
the euglenoid has chloroplasts
Term
what are three categories of non-euglenoid flagellated protozoans?
Definition
kinetoplastids, diplomonads, parasilids
Term
two examples of a kinetoplastid
Definition
Trypanosoma (african sleeping sickness) and T. Cruzi (chagas disease)
Term
example of a diplomonad
Definition
giardia lambia
Term
parasilid example
Definition
trichomonas vaginalis
Term
what are the two categories of the Phylum Sarcodina?
Definition
Rhizopods, actinopods
Term
two types of rhizopods?
Definition
naked ameobas and foraniferans
Term
two kinds of actinopods
Definition
radiolarans and heliozoans
Term
four divisions of the phylum chrysophyta:
Definition
golden algae, yellow-green algae, coccolithophovies, diatoms
Term
what is phylum phaeophyta
Definition
brown algae
Term
what is phylum chlorophyta?
Definition
green algae
Term
what is phylum rhodophyta?
Definition
red algae
Term
what kind of organisms make up phylum phyrrhophyta?
Definition
dinoflagellates
Term
what kind of organisms make up the phylum apicomplexa?
Definition
sporozoans
Term
how do euglenoids recieve their nutrients?
Definition
photoautotrophic and heterotrophic
Term
what is special about the euglenoid body plan?
Definition
have flagella and light sensitive eye spot.
Term
are non-euglenoid flagellated protozoans photoautotrophic or heterotrophic?
Definition
heterotrophic
Term
how many flagella do non-euglenoid flagellated protozoans have?
Definition
one or more
Term
how do naked ameobas get their nutrients?
Definition
phagocytosis
