Watch the video about the
wacky history of the cell
theory. It is located on my
website.
Your notes…
Place all notes on right side of N21.
You should know the three
principles of the cell theory, the
scientists that are important in the
discovery of cells, and the
differences between prokaryotic
and eukaryotic cells. I suggest
sketch notes, but you can use
whatever format you like.
What are the three principles to
the cell theory?
All organisms are composed of
A ________
one or more cells.
Basic
________ units of structure, organization
B and function in all organisms.
C
Cells
________ come from preexisting cells.
Who was Zacharias Janssen?
He made the first known
_______________
compound microscope in
1595.
Who was Anton VanLeeuwenhoek?
He made the first __________
single lens
microscope and discovered
one-celled organisms including,
bacteria in 1676.
Who was Robert Hooke?
He used
microscopes to
look at cork
and coined the
term __________
cells
in 1665.
Who was Matthias Schleiden?
plants
He concluded that all __________

Who was Theodor Schwann?
He concluded that all animals
__________

Your notes…
Do you have the three principles of
the cell theory, the scientists that
are important in the discovery of
cells, and the differences between
prokaryotic and eukaryotic cells?
If you answered no, go back and fix
your notes.
