CERTIFICATION PREPARATION 2026 REVIEW
SHEET SOLVED QUESTIONS GUARANTEED
PASS
◉ Robert Hooke.
Answer: • 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.
Answer: • 1st cells observed under the microscope
also made the original electron microscope : 10 mil X
◉ Rebecca Lancefield.
Answer: • came up with the system that help classifying different
microorganisms
• it was all based on different polysaccharides in the cell wall
also helped discover Streptococcus pyognes - which is basically
strep and we know this because pyognes is a pus forming
microorganism
,◉ Joseph Lister.
Answer: • discovered phenol: was used to stop surgical would
infections
• usually in hospitals : Staphylococcus aures aka staph infection

they carry it in their noses
◉ Louis Pasteur.
Answer: • father of microbiology and is the most important scientist
in microbiology
• showed that microbes are responsible for fermentation
• Fermentation: conversion of sugar to alcohol in the absence of air
• Discovered that pasteurization was something that could stop food
spoilage
• Pasteurization: the application of a high heat for a short time to kill
harmful bacteria in beverages
How was he lucky in his discovery of pasteurization?—there we're
no endospores and that would should have been detected during the
search for spontaneous generation but it didn't
◉ Robert Koch.
Answer: Proved that bacterium causes anthrax and provided the
experimental steps of Koch's Postulate
, ◉ Edward Jenner.
Answer: • Discovered vaccination (or the process of vaccination)
Did it through using cow parts to vaccinate a child to protect against
small pox

◉ Agostino Bassi.
Answer: Believed that silk worm disease was caused by a fungus
◉ Ignaz Semmelweis.
Answer: • 1st person that came up with hand washing
starting with delivering babies and babies we're dying and then
when they washed their hands the death rate when way down
◉ Woes.
Answer: discovered the 3 domains and they were all based on the
