What is a microbe? How small does an organism have to be to be
considered a microbe? - 🧠ANSWER ✔✔A microbe is a living organism that
requires a microscope to be seen. Microbe diameter must be less than 0.15
mm.
,True or false: Some microbes can consist of a single cell. - 🧠ANSWER
✔✔True.
A _____ is the total genetic information contained in an organism's
chromosomal DNA. - 🧠ANSWER ✔✔Genome.
What developed the first method of DNA sequencing fast enough to
sequence large genomes? - 🧠ANSWER ✔✔Fred Sanger.
What is a collection of sequences taken directly from the environment
called? - 🧠ANSWER ✔✔A metagenome.
Ture or false: Each microbe has the capacity to reproduce its own kind. -
🧠ANSWER ✔✔True.
What is a cell community? - 🧠ANSWER ✔✔Many of the same kind of cell.
Should plant and animal cells be considered microbes? - 🧠ANSWER
✔✔No. Plant and animal cells cannot reproduce their own kind indefinitely.
Additionally, animal cells are differentiated and do not exist as
independently or as communities.
What types of organisms are considered microbes? - 🧠ANSWER
✔✔Bacteria, Archaea, Algae, Fungi, protists, and Viruses.
,What 14th century disease was caused by microbes? - 🧠ANSWER
✔✔bubonic plague.
What is Florence Nightingale famous for? - 🧠ANSWER ✔✔Florence
Nightingale was the first to recognize the significance of disease in warfare.

What is Robert Hooke famous for? - 🧠ANSWER ✔✔Built the first
compound microscope.
Coined the term "cell".
Published the first manuscript that illustrated objects under the microscope.
What is Antonie Van Leeuwenhoek famous for? - 🧠ANSWER ✔✔First to
observe single-cell microbes moving around. He observed samples from
his mouth under the microscope, saw them moving around and called them
small animals.
He built the first primitive microscope with the intention to observe fine
fabrics (he was a cloth draper).
Who discovered the microbial basis of fermentation? How did this person
do this? - 🧠ANSWER ✔✔Louis Pasteur. He built a swan-neck flask and

, showed that after boiling, the contents remain free of microbial growth
despite access to air.
What scientists disproved the theory of spontaneous generation of
microbes? - 🧠ANSWER ✔✔Francesco Redi: showed that maggots in
decaying meat were the offspring of flies.
Lazzaro Spallanzani: showed that a sealed flask of meat broth sterilized by
boiling failed to grow microbes.
Louis Pasteur: showed that after boiling, the contents in the swan neck
flask remain free of microbial growth.
Who is considered the Founding Father of Microbiology? - 🧠ANSWER
✔✔Louis Pasteur.
What is the Germ Theory of Disease? - 🧠ANSWER ✔✔That many diseases
are caused by microbes (most infectious diseases).
Who is the founder of the scientific method of microbiology? - 🧠ANSWER
✔✔Robert Koch.
