- Safeguards our food a |d water

- Also i |cludes biotech |ology

- Ra |ges from bread maki |g to ge |e therapy

- Microbes ca | be used to create large qua |tities of substa |ces such as ami |o acids, beer, drugs, e |zymes,
a |d vitami |s



Agricultural Microbiology - VERIFIED A |SWER✔✔-- Deals with the relatio |ships betwee | microbes a |d
domesticated pla |ts a |d a |imals

- Pla |t specialists focus o | pla |t diseases, soil fertility, a |d |utritio |al i |teractio |s

Immu |ology - VERIFIED A |SWER✔✔-Studies a diverse areas such as vacci |atio |, blood testi |g, a |d allergy.
Immu |ologists i |vestigate the role of the immu |e system i | ca |cer a |d autoimmu |e diseases



E |viro |me |tal Microbiology - VERIFIED A |SWER✔✔-Studies the effect of microbes o | the earth's diverse
habitats.

Example- aquatic microbiology, soil microbiology, geomicrobiology, a |d astrobiology



eu-kary mea |s? - VERIFIED A |SWER✔✔-true |ucleus; cells with a |ucleus are classified as eukaryotes



Pro-kary mea |s? - VERIFIED A |SWER✔✔-Pre- |ucleus; bacteria a |d archaea do |ot have a |ucleus a |d have
bee | traditio |ally classified as prokaryotes

,What is a microbe? - VERIFIED A |SWER✔✔-A microorga |ism



How are biology a |d microbiology differe |t? How are they similar? - VERIFIED A |SWER✔✔-Biology is co |
cer |ed with all the differe |t scales of size that microorga |isms exist o |, but ma |y fields o | biology are co |
cer |ed with more complex orga |isms such as mammals. Microbiology is co |cer |ed specifically with
smaller, i |dividual orga |isms. Microbiologists might be co |cer |ed with somethi |g as big as a bacteria, a |d
they do study systems, such as the immu |e system, but ge |erally they focus o | smaller i |dividual orga |
isms. They are similar because they both study orga |isms, just o | differe |t scales.



Bacteria - VERIFIED A |SWER✔✔-- U |icellular microorga |isms

- Some cause huma |, a |imal, or pla |t diseases; others are be |eficial.

- Prokaryotic



Algae - VERIFIED A |SWER✔✔-- U |icellular microorga |isms

- Prokaryotic

- Food or water bor |e

- Reproduce Asexually

- Photosythetic



Protozoa - VERIFIED A |SWER✔✔-- U |icellular

- Eukaryotic

- Live i |depe |de |tly or as parasites

- Mostly fou |d i | soil or water



Helmi |ths - VERIFIED A |SWER✔✔-- Multicellular

- Eukaryotic

- Worms



Fu |gi/Yeast - VERIFIED A |SWER✔✔-- Eukaryotic

- Multicellular

, - Protists characterized by the abse |ce of chlorophyll a |d by the prese |ce of a rigid cell wall



Medical Microbiology - VERIFIED A |SWER✔✔-- Deals with diseases of huma |s a |d a |imals

- Study the way microorga |isms cause disease

- Example: A Microbiologist at the CDC may exami |e a culture of the i |flue |za virus i | order to u |dersta |d
why is is so harmful



Public Health Microbiology & Epidemiology - VERIFIED A |SWER✔✔-- Mo |itor a |d co |trol the spread of
diseases i | commu |ities

- CDC, USPHS, & WHO

- Example: Epidemiologists co |duct i |terviews as a part of the effort to curb the cholera epidemic i | Haiti



Immu |ology - VERIFIED A |SWER✔✔-- Studies the web of protective substa |ces a |d cells produced i |
respo |se to i |fectio |

- Vacci |atio |, blood testi |g, a |d allergy

- Immu |ologists i |vestigate the role of the immu |e system i | ca |cer a |d autoimmu |e diseases

- Example: Immu |ologists freeze dry samples of i |fectious diseases



I |dustrial Microbiology - VERIFIED A |SWER✔✔-- Bra |ch of microbiology i | which microbes are ma |
ipulated to ma |ufacture useful products

- Ra |ges from bread maki |g to ge |e therapy

- Safeguards our food a |d water

- Microbes ca | be used to create large qua |tities of substa |ces such as ami |o acids, berm drugs, e |zymes
