WITH COMPLETE SOLUTIONS
ALREADY PASSED!!!
What is the definition of microbiology?
✔✔ The specialized area of biology that deals with living organisms and
infectious entities too small to be seen clearly with the naked eye
(microorganisms or microbes).
What are the six major groups of microorganisms studied in microbiology?
✔✔ 1. Bacteria (and Archaea)
✔✔ 2. Algae
✔✔ 3. Protozoa
✔✔ 4. Helminths (parasitic worms, included due to microscopic life stages and
diagnostic overlap)
✔✔ 5. Fungi (molds and yeasts)
✔✔ 6. Viruses (and other acellular infectious agents like prions)
What core biological aspects and characteristics do microbiologists study
regarding microorganisms?
✔✔ Cell structure (anatomy and ultrastructure)
✔✔ Growth and physiology (metabolism and replication)
✔✔ Genetics (molecular biology and gene transfer)
✔✔ Taxonomy and evolutionary history (phylogeny and classification)
✔✔ Interactions with living and non-living environments (ecology,
pathogenesis, and symbiosis)
What are the six primary branches of study within the field of microbiology?
,✔✔ 1. Medical microbiology (pathogens, human disease, and clinical
diagnostics)
✔✔ 2. Public health microbiology and epidemiology (disease spread,
monitoring, and control)
✔✔ 3. Immunology (host defense mechanisms, immunity, and allergy)
✔✔ 4. Industrial microbiology (biotechnology, food/beverage production, and
pharmaceutical manufacturing)
✔✔ 5. Agricultural microbiology (plant-microbe and animal-microbe
interactions, soil fertility)
✔✔ 6. Environmental microbiology (microbial ecology, bioremediation, and
biogeochemical cycles)
Medical Microbiology -ANSWER✔✔Study of microbes as they relate to
medicine, deals with microbes that causes disease in humans and animals
Public Health Microbiology and Epidemiology -ANSWER✔✔Monitor and control
the spread of disease in communities. USPHS, CDC, WHO
Industrial Microbiology -ANSWER✔✔- Use of microbes to manufacture
important compounds
- Safeguards our food and water
- Also includes biotechnology
- Ranges from bread making to gene therapy
- Microbes can be used to create large quantities of substances such as amino acids,
beer, drugs, enzymes, and vitamins
Agricultural Microbiology -ANSWER✔✔- Deals with the relationships between
microbes and domesticated plants and animals
,- Plant specialists focus on plant diseases, soil fertility, and nutritional interactions
- Animal specialists work with infectious diseases and other associations animals
have with microorganisms
Immunology -ANSWER✔✔Studies a diverse areas such as vaccination, blood
testing, and allergy. Immunologists investigate the role of the immune system in
cancer and autoimmune diseases
Environmental Microbiology -ANSWER✔✔Studies the effect of microbes on the
earth's diverse habitats.
Example- aquatic microbiology, soil microbiology, geomicrobiology, and
astrobiology
eu-kary means? -ANSWER✔✔true nucleus; cells with a nucleus are classified as
eukaryotes
Pro-kary means? -ANSWER✔✔Pre-nucleus; bacteria and archaea do not have a
nucleus and have been traditionally classified as prokaryotes
What is a microbe? -ANSWER✔✔A microorganism
How are biology and microbiology different? How are they similar? -
ANSWER✔✔Biology is concerned with all the different scales of size that
microorganisms exist on, but many fields on biology are concerned with more
complex organisms such as mammals. Microbiology is concerned specifically with
smaller, individual organisms. Microbiologists might be concerned with something
as big as a bacteria, and they do study systems, such as the immune system, but
generally they focus on smaller individual organisms. They are similar because
they both study organisms, just on different scales.
, Bacteria -ANSWER✔✔- Unicellular microorganisms
- Some cause human, animal, or plant diseases; others are beneficial.
- Prokaryotic
Algae -ANSWER✔✔- Unicellular microorganisms
- Prokaryotic
- Food or water borne
- Reproduce Asexually
- Photosythetic
Protozoa -ANSWER✔✔- Unicellular
- Eukaryotic
- Live independently or as parasites
- Mostly found in soil or water
Helminths -ANSWER✔✔- Multicellular
- Eukaryotic
- Worms
Fungi/Yeast -ANSWER✔✔- Eukaryotic
- Multicellular
- Protists characterized by the absence of chlorophyll and by the presence of a rigid
cell wall
