MICROBIOLOGY FOR COMLEX LEVEL 1 EXAM REVIEW UPDATED FINAL EXAM 2026
Microbiology Exam 1
Microorganism
are organisms that are too small to see with the unaided eye
examples of microorganisms
bacteria
fungi
protozoa
microscopic algae
viruses
what kind of microscope do you use when you are working with microorganisms you can't
see?
bright field microscope
what are the different magnifications of a bright field microscope
4x
10x
40x
100x
what is the kind of microscope that you use when looking at a virus
electron microscope
what are the different magnifications of the electron microscope
1 mil
2 mil
10 mil
How are microbes helpful
,decompose organic waste
generate O2
produce chemical products such as ethanol and others
produce fermented foods ex: vinegar, cheese, and bread
produce products used in manufacturing ex: cellulose and insulin
How many microbes are pathogenic out of all the microorganisms
70/10 mil
what knowledge do microbes give humans
prevent diseases
allow food storage and prevent food spoilages
stop transmission of diseases
Microbiology
the study of organisms too small to be seen with the naked eye
microbial ecology
the study of the relationship between microorganisms and their environment
competitive exclusion
a way to kill the bad bacteria
- change in the pH
- secrete enzymes
- eat the food
bioremediation
using microbes to clean up pollutants
Bacillus thuringienisis
can kill insects but doesn't harm plants or animals
, Order of the Scientific Method
observe
hypothesis
prediction
experiment
consistency
theory
law
Mycology
study of fungi
bacteriology
study of bacteria
virology
study of viruses
algology
study of algae
protozoology
study of protozoa
Robert Hooke
• All living organisms are composed of little boxes or "cells"
• -came up with cell theory - that all microorganisms are made up of cells
-marked the beginning of the cell theory
Anton van Leeuwenhook
• 1st cells observed under the microscope
also made the original electron microscope : 10 mil X
