Name the six kingdoms of life. Tell
whether they are prokaryotic or eukaryotic.
- Bacteria (prokaryotic)
- Archaea (prokaryotic)
- Protista (eukaryotic)
- Fungi (eukaryotic)
- Plantae (eukaryotic)
- Animalia(eukaryotic)
-
How does one distinguish whether an organism is prokaryotic or
eukaryotic?
Eukaryotic cells have organelles. Prokaryotic cells do not.
-
Where does the energy to fuel most organisms come from originally?
The sun; photosynthesis
-
How do nutrients make their way back into the soil?
Decomposition
-
Define ubiquitous
"everywhere"
-
What is thought to cause gastric ulcers in humans?
Helicobacter, drugs
-
Parasite-
an organism that feeds on another living organism
-
Host -
an organism that has a parasite.
-
Who invented the microscope?
Leeuwenhoek
-
Who introduced the germ theory of disease?
Pasteur
-
Who developed a plan to determine whether a particular “germ” caused a specific disease?
Koch
-
What type of organism are you? Be
sure to use standard binomial nomenclature.
Homo sapiens
-
In a cell culture, a mound of bacteria is called a...
colony
-
In lab, we grow bacterial cultures in...
agar
-
If you culture something, and get several types of colonies, how can you get pure cultures for identification?
(isolate and reculture)
-
What is the difference in magnification and resolution?
Magnification – how big it is
Resolution – how clear the picture is
-
What kingdoms of life are made up of
bacteria?
Archae, Bacteria
-
Archae that live in swamps and produce
methane are called
methanogens
-
Archae that live in extremely salty places
are called
halophile
-
Archae that live in very hot places are
called
thermophile
-
Rod shaped bacteria are called
bacilli
-
Sphere shaped bacteria are called
cocci
-
Spiral shaped bacteria are called
spirilla
-
Chains of cocci are called
Streptococci
-
Clusters of cocci are called
Staphylococci
-
Gram-positive bacteria stain
Purple
-
Gram-negative bacteria stain
pink
-
Bacteria that normally live in the
intestinal tract of animals including humans are called
methanogens
-
Bacteria that extract energy from minerals
(no sun needed) are called
Chemoautotroph
-
Bacteria that live on the roots of plants
(legumes) and change nitrogen into a usable form are called
nitrogen fixing bacteria
-
Bacteria typically reproduce by
binary fission
-
When two bacteria bind together and
exchange transfer genetic material, it is called
conjugation
-
A long structure that moves bacteria along
is called a
flagella
-
Bacteria that feed on dead things are
called
decomposers, detritivores
-
Bacteria that use the sunlight as an energy
source are called
Photoautotroph
-
Bacteria that cannot survive in the
presence of oxygen are called
Obligate Anaerobes
-
Bacteria that can live without oxygen or
with oxygen are called
Facultative Anaerobes
-
Bacteria that cannot survive without oxygen
are called
Obligate Aerobes
-
Bacteria that grow in hot environments are
called
thermophile
-
Drugs that are produced in a laboratory to
fight bacterial infections are called
antibiotics
-
How do bacteria develop antibiotic
resistance?
The population evolves into a resistant strain because the bacteria that are not resistant die.
-
List 5 things that are useful about
bacteria.
- make antibiotics
- make vitamins
- make insulin
- make cheese, yogurt
- decomposers/recycling
-
Why is a virus not considered to be alive?
- It is not cellular.
- It cannot grow, reproduce, etc. without invading a host cell.
