MICROBIOLOGY EXAM QUESTIONS
AND ANSWERS (CHAPTER 1,3,4,5,6)
Microbiology - CORRECT ANSWER-The specialized area of
biology that deals with organisms too small to be seen with the
naked eye
6 major groups of microorganisms - CORRECT ANSWER-1.
Bacteria
2. Algae
3. Protozoa
4. Helminths
5. Fungi
6. Viruses
What do microbiologists study? - CORRECT ANSWER-- Cell
structure
- Growth and Physiology
- Genetics
- Taxonomy and evolutionary history
- Interactions with living and non living environment
What are the 6 different branches of study in microbiology? -
CORRECT ANSWER-1. Medical microbiology
2. Public Health microbiology and Epidemiology
3. Immunology
4. Industrial Microbiology
Medical Microbiology - CORRECT ANSWER-Study of microbes
as they relate to medicine, deals with microbes that causes
disease in humans and animals
Public Health Microbiology and Epidemiology - CORRECT
ANSWER-Monitor and control the spread of disease in
communities. USPHS, CDC, WHO
Industrial Microbiology - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT ANSWER-Studies the
effect of microbes on the earth's diverse habitats.
Example- aquatic microbiology, soil microbiology,
geomicrobiology, and astrobiology
,eu-kary means? - CORRECT ANSWER-true nucleus; cells with
a nucleus are classified as eukaryotes
Pro-kary means? - CORRECT ANSWER-Pre-nucleus; bacteria
and archaea do not have a nucleus and have been traditionally
classified as prokaryotes
What is a microbe? - CORRECT ANSWER-A microorganism
How are biology and microbiology different? How are they
similar? - CORRECT 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 - CORRECT ANSWER-- Unicellular microorganisms
- Some cause human, animal, or plant diseases; others are
beneficial.
- Prokaryotic
Algae - CORRECT ANSWER-- Unicellular microorganisms
- Prokaryotic
- Food or water borne
- Reproduce Asexually
- Photosythetic
Protozoa - CORRECT ANSWER-- Unicellular
- Eukaryotic
- Live independently or as parasites
- Mostly found in soil or water
Fungi/Yeast - CORRECT ANSWER-- Eukaryotic
- Multicellular
- Protists characterized by the absence of chlorophyll and by
the presence of a rigid cell wall
Medical Microbiology - CORRECT ANSWER-- Deals with
diseases of humans and animals
- Study the way microorganisms cause disease
- Example: A Microbiologist at the CDC may examine a culture
of the influenza virus in order to understand why is is so
harmful
Public Health Microbiology & Epidemiology - CORRECT
ANSWER-- Monitor and control the spread of diseases in
communities
- CDC, USPHS, & WHO
- Example: Epidemiologists conduct interviews as a part of the
effort to curb the cholera epidemic in Haiti
Immunology - CORRECT ANSWER-- Studies the web of
protective substances and cells produced in response to
infection
- Vaccination, blood testing, and allergy
- Immunologists investigate the role of the immune system in
cancer and autoimmune diseases
- Example: Immunologists freeze dry samples of infectious
diseases
Industrial Microbiology - CORRECT ANSWER-- Branch of
microbiology in which microbes are manipulated to
manufacture useful products
- Ranges from bread making to gene therapy
- Safeguards our food and water
