Question 21.
Robert Hooke
Correct 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
Question 22.
Anton van Leeuwenhook
Correct Answer: • 1st cells observed under the microscope also made the
original electron microscope : 10 mil X
Question 23.
Rebecca Lance-field
Correct 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
