vital role of microbes - ANSWER marine and freshwater are the bottom of the food
chain. soil microbes responsible for breaking down waste and providing nitrogen to the soil,
many are photosynthetic. some microbes in the intestines help manufacturing vitamins that
cannot be made.
which are the 2 names that the microorganisms have? - ANSWER - genus
- species
what are the characteristic when writing the name of a microbe? - ANSWER - both the
genus and the species are italicized
- genus name is always capitalized
- specie is always lowercase
- must have both f the names
- Abbreviation of the genus name is also acceptable, as long as you have used the name
previously --The abbreviation is always the first letter of the genus, and the entire species
name
-NOT THE SAME RULES FOR VIRUSES
the scientific name of a microbe always refer to the ___________ or the ____________ -
ANSWER shape, environment
What does staphylo mean? - ANSWER clustering shape of cells
1
,What does coccus mean? - ANSWER the shape of the bacterium
What does aureus mean? - ANSWER Latin for golden; refers to the color of many
Staphylococcus aureus colonies.
what is microbiology - ANSWER it is defined as the study of small microorganisms
which cannot be seen with the unaided eye:
- fungi
- bacteria
- yeast
- molds
- viruses
- parasites
pathogens - ANSWER the opposite of nonpathogen. microbes that make us sick
what is common in all microorganisms - ANSWER they all have 2 names ( genus and
specie )
what are the 3 common shapes of bacteria - ANSWER - bacillus or rod
- coccus
- spirillum or spiral
what is the classification of viruses - ANSWER - capsid: have a DNA or RNA core
surrounded by a high structure protein coat
- enveloped: have a capsid but are encased in a lipid membrane, usually taken from a host
cell.
2
, who classified microbes based of their cell structure? when ? - ANSWER 1978, Carl
Woese:
- Arcaea
- Bacteria
- Eukarya ?
who discovered the cell and when? - ANSWER 1665, Robert Hooke
Discovery of the cell by Robert Hooke.
Observed cells of dried cork wood using a crude "microscope"
Determined that there were little compartments within the cork he termed cells
This marks the beginning of cell theory, the theory that all living things are composed of cells
Who invented the 1st microscope? when? - ANSWER 1673: Antoni von Leeuwenhoek
invents the microscope and observes the first microbes.
First true microscope, used to observe living organisms
Described what he saw as "animalcules"
His prodigious notes have allowed for the determination that he was observing bacteria and
protozoa
who introduced the idea of microbes being in the air and the idea of biogenesis, not
spontaneous generation? when? - ANSWER 1861: Louis Pasteur
chemist who was studying fermentation
Major problem of the day for wine and beer production was spoilage
He observed both larger (yeast) and smaller (bacterial) cells in finished products that had
spoiled
The smaller cells were absent from unspoiled product
