Scope of Microbiology Flashcards
Are bacteria multicellular or unicellular?
Unicellular
Do bacterial cells have a nucleus?
no
do bacterial cells have peptidoglycan?
yes
do bacterial cell membranes contain a phospholipid bilayer or monolayer?
phospholipid bilayer
how do bacterial cells divide?
binary fission
how do bacterial cells get their nutrition from?
photosynthesis
domain:
is the largest classification group
domain contains which three groups?
bacteria, archaea, eukaryara
is archaea multicellular or unicellular
unicellular
do archaea have a nucleus
no
is bacteria considered prokaryote or eukaryote?
prokaryote
is archaea considered prokaryote or eukaryote?
prokaryote
archaea cell walls lack
peptidoglycan
do archaea cell membranes contain a phospholipid bilayer or monolayer?
phospholipid monolayer
archaea can be (temperature)
extremophiles
not generally pathogenic
archaea
cannot be killed by antibiotics
archaea
have DNA inside nucleus
eukaryotes
Eukaryotes are what type of organisms
unicellular and multicellular
can bacterial cells be killed by antibiotics
yes
considered pathogenic
bacterial cells
is Kingdom Fungi considered a prokaryote or eukaryote
Eukaryote, DNA with nucleus
contains chitin cell walls
Kingdom Fungi
are yeasts unicellular or multicellular
unicellular
are molds and mushrooms considered unicellular or multicellular
multicellular
Mycelia with filamentous hyphae
Kingdom Fungi
Heterotrophic multicellular eukaryotes
Kingdom Animalia
can be vectors of microbial pathogen
Kingdom Animalia
not strictly microbes (helminths)
Kingdom Animalia
Flatworms and roundworms are examples of
Kingdom Animalia
protozoan and algae
Kingdom Protista
Kingdom Protista is considered a
eukaryote
absorb or ingest organic chemicals
Kingdom Protista- Protozoa
some are photosynthetic
Kingdom Protista- protozoa
Free living or parasitic
(derive nutrients from a living host)
Kingdom Protista- Protozoa
Kingdom Protista- Protozoa reproduces
sexually or asexually
Which kingdom has cellulose cell walls?
Kingdom Protista- Algae
Kingdom Protista- Algae is considered to be eukaryote or prokaryote
eukaryote
where is Kingdom Protista- Algae found?
freshwater, saltwater and soil
use of photosynthesis for energy, produces oxygen and carbohydrates
Kingdom Protista- Algae
Kingdom Protista- Algae reproduces how
both sexual and asexual reproduction Is possible
Is a virus acellular or multicellular
Acellular
A virus core consists of
DNA or RNA
Who has a core that is surrounded by a protein core?
Virus
Coat may be enclosed by a lipid envelope
Virus
viruses are replicated only when
they are in a living host
where do viruses inert
outside living hosts
group of microbes that live stably on/in the human body
Microbiome
are viruses obligate parasites?
yes
help maintain good health
can prevent growth of pathogenic microbes
may help train immune system to discriminate threates
begin to be acquired as newborns at body sites with right conditions
can colonize the body indefinitely or fleetingly (transient microbiota)
Normal microbiota
organisms that are too small to be seen with the unaided eye
microorganisms
understanding the structure and functions of microbes
microbiology
disease producing
pathogenic
the science of classification
taxonomy
a classification group
taxon
binomial nomenclature
Carolus Linnaus
the largest classification group
domain
Beginning of Cell theory
“all living things are composed of cells”
Robert Hooke
Cork (cells)
Robert Hooke
Animalcules
Anton Van Leeuwenhoek
experiment that maggots wouldn’t grow on meat if first covered
Francisco Redi
who supported biogenesis
Fransisco Redi
Disproved spontaneous generation
Louis Pasteur
S shaped flask
LPasteur
Pasteurization
LPasteur
s- shaped flask, pasteurization, silkworm was caused by fungus
LPasteur
Advocated hand washing to prevent transmission of microbes
Ignaz Semmelweis (semmelwash)
directly linked specific microbe to specific disease
Robert Koch
Antibiotic
Alexander Fleming
found that penicillin(mold) antibiotic killed Staphylococcus aureus
