Microbiology - ANSWER:the specialized area of biology that deals with organisms too
small to be seen with the naked eye
Major groups of microorganisms - ANSWER:Bacteria
Algae
Protozoa
Helminths
Fungi
Viruses: noncellular, parasitic, protein-coated genetic elements
Microbiologists study - ANSWER:Cell structure and function
Growth and physiology
Genetics
Taxonomy and evolutionary history
Interactions with living and nonliving environment
Microbiology includes various branches of study: - ANSWER:Medical Microbiology
Public health Microbiology and Epidemiology
Immunology
Industrial Microbiology
Agricultural Microbiology
Environmental Microbiology
eukaryotes - ANSWER:Cells with a nucleus
prokaryotes - ANSWER:small cells, lacking special structures such as nucleus and
organelles, all procaryotes are microorganisms
Bacteria are ubiquitous (found everywhere). They are found: - ANSWER:Deep in the
earth's crust
Polar ice caps
Oceans
Inside the bodies of plants and animals
Evolution - ANSWER:the accumulation of changes that occur in organisms as they
adapt to their environments.
Theory of Evolution - ANSWER:Documented every day in all corners of the planet
An observable phenomenon testable by science
A label for a well-studied and well-established natural phenomenon
, Microbes are deeply involved in ________. - ANSWER:the flow of energy and food
through the earth's ecosystems.
What kind of photosynthesis do bacteria use and what does it mean? -
ANSWER:anoxygenic photosynthesis-
Anoxygenic photosynthesis is the phototrophic process where light energy is
captured and converted to ATP, without the production of oxygen. Water is
therefore not used as an electron donor.
Photosynthetic microorganisms account for more than ____% of the earth's
photosynthesis - ANSWER:70
Decomposition - ANSWER:Breakdown of dead matter and wastes
Accomplished by bacteria and fungi
Microbes are the main forces that drive: - ANSWER:the structure and content of soil,
water, and atmosphere.
Where is bacteria found? - ANSWER:deep in the earth's crust (most abundent), polar
ice caps, oceans, and inside the bodies of plants and animals
True/False: Microscopic organisms produce more oxygen than plants - ANSWER:True
True/False: More than 50% of the microbes on the planet live below the Earth's crust
- ANSWER:True
Biotechnology: - ANSWER:manipulation of microorganisms to make products in an
industrial setting
Genetic Engineering - ANSWER:manipulates the genetics of microbes, plants, and
animals for the purpose of creating new products and genetically modified
organisms (GMOs)
Recombinant DNA technology - ANSWER:Techniques that allow the transfer of
genetic material from one organism to another and deliberately alter DNA
Bioremediation - ANSWER:introduction of microbes into the environment to restore
stability or to clean up toxic pollutants
Name three products produced by genetically modified organisms that benefit
humans. - ANSWER:drugs, hormones and enzymes
Describe one method in which microbes are used for bioremediation. -
ANSWER:Treatment of water and sewage
