organisms appear on earth?
1.8 billion years - Answer How long ago did eukaryotic organisms arise?
They are everywhere and occupy every possible habitat on earth - Answer Microorganisms
are ubiquitous-this means what?
Used in the making of medicines, vaccines, bakery such as bread, replenishes the soil, helps
create oxygen, used in water treatment, is found in our intestines to help digest, fermentation,
aids in the making of alcohol (wine), used in biotechnology - Answer What are 10 ways that
microorganisms are important to humans?
Pathogen - Answer What is an organism or microbe that causes disease?
Spontaneous generation - Answer What is the belief that invisible vital forces present in non-
living, decaying matter led to the creation of living organisms?
Abiogenesis - Answer Term for beginning in absence of life?
Biogenesis - Answer Term for beginning with life?
Modern uses of microbes - Answer Genetic engineering, recombinant DNA technology, and
bioremediation are all what?
,Francesco redi - Answer Who was is that challenged, or discredited spontaneous generation
by showing that maggots on decaying meat came from fly eggs?
John needham - Answer Who was is who put mutton broth in flasks/jars, barely boiled it,
and then sealed it resulting in the broth becoming cloudy and containing microorganisms?
Lazzaro spallanzani - Answer Who put the broth in flasks, sealed it, then boiled for a longer
time resulting in no growth of microorganisms.
Louis Pasteur - Answer Who studied the role of microorganisms in fermentation of alcohol
beverages, developed the rabies vaccine, and set the foundation for the germ theory-he also
developed the flasks with a seal that hand a long spout on the end that caught dust before it
reached the broth?
John Tyndall - Answer Who demonstrated that dust does carry microorganisms, and if no
microorganisms were in the dust, then there would be no growth?
Ferdinand Cohn - Answer Who showed that heat resistant bacteria could produce
endospores?
Robert Hooke - Answer Who was credited for making the earliest recorded observations
with a magnifying glass and established the word "cell"?
Leeuwenhoek - Answer Who grinder lenses so far down that he was able to record the first
accurate observations and descriptions of the things that we cannot see with the naked eye that
are living?
Miasma and imbalance in the four humors of the body - Answer Back in the day, it was the
belief that diseases were due to what two things?
Liver Wendell Holmes - Answer Who observed that homes births were much safer than
hospital births?
Ignaz Semmelweis - Answer Who showed the importance of washing hands and stated that
disease was transmittable through not doing so?
John snow - Answer Who traced a water borne illness and stated that diseases are
transmittable through water?
, Joseph lister - Answer Who provided the first indirect evidence that microorganisms cause
disease. He is known by "listerine". Developed a system of surgery designed to prevent
microorganims from entering wounds as well as methods for treating instruments and surgical
dressings.
Robert koch - Answer This man provided the first evidence that microorganisms cause
disease. He developed a series of steps that verified the germ theory of disease and established
a link between a microbe and the disease it caused (bacillus anthracis). He worked
with/devolved/discovered anthrax!
Robert koch - Answer Who was credited for developing pure culture techniques?
Prokaryotic - Answer This type of cell has no nucleus, no membrane bound organelles, is 10
times smaller than the other type of cell, has structures that function the same way organelles
do, and all are microorganisms?
Eukaryotes - Answer Which cell does contain organelles and is found in humans, plants,
fungi, and Protozoa?
Viruses - Answer These are acelluar infectious agents, obligate intracellular parasites and are
not independently living cellular organisms, composed of hereditary material (DNA or RNA but
not both), and a protein coat, and are inside a host organisms-what are these all characteristics
of?
Nomenclature - Answer What is the assignment of scientific names to various taxonomic
categories and to individual organisms?
Classification - Answer What is organizing organisms until descending ranks, beginning with a
general all-inclusive taxonomic category ending with the smallest and most specific category?
Identification - Answer What is the process of discovering no recording the traits or
organisms so they can be named and placed into proper taxonomic ranking?
Binomial system of nomenclature - Answer What is it called when we talk of the system used
to name organisms such as bacteria-including the fact that it has a genus and a species, the
scientific names are italicized, and sometimes underlined, and sometimes can be abbreviated
after the first use-what is this system called?
Carl von linne - Answer Who developed the binomial system of nomenclature?
