Lectures 1 & 2
the study of microscopic life
o life so small, a microscope is needed for viewing
ancestors of all other life
o archeao bacteria: first life to emerge on our planet and could live in harsh
Lecture 3: The Chemistry of Biology
Atoms, Bonds, and Molecules
matter: all material that occupy space and have mass
o matter is composed of atoms
atom: simplest form of matter not divisible into simpler substances
o protons: (+): subatomic
Lecture 6: A Survey of Prokaryotic Cells and Microorganisms
Characteristics of Cells and Life
all living things (single and multicellular) are made of cells that share common
o basic shape: spherical, cubical, cylindrical
Lecture 7: A Survey of Eukaryotic Cells and Microorganisms
they first appeared approximately 2 billion years ago
evidence suggests evolution from prokaryotic organisms by symbiosis
organelles originated from prokaryotic cells trapp
Lecture 9: Chemical Agents
antimicrobial agents- a chemical used to kill or inhibit the growth of microorganisms
sterilant- a chemical that causes sterilization meaning you have destroyed or removed all
microorganisms from an ob
Lecture 10: Drugs, Microbes, Host- The Elements of Chemotherapy
Principles of Antimicrobial Therapy
administer a drug to an infected person that destroys the infective agent without harming
the hosts cells
antimicrobial drugs are produced n
Lecture 4: Tools of the Laboratory/ The Methods for Studying Microorganisms
key characteristics of a reliable microscope are:
o magnification: ability to enlarge objects
o resolving power: ability to show detail; limits useful
Lecture 5: Characterizations of Microorganisms
pure culture: one single organism type in a culture (all identical from one parent cell)
mixed culture: more than one organism (the way we find things in nature)
culture media: wha
