The Cell Theory Timeline Project
• Using your notes, create a timeline showing who Janssen, Hooke,
Leeuwenhoek, Schleiden, Schwann, and Virchow where and how
they contributed to scientific understanding of cells.
• Be sure to include the scientists pictures.
• Use the legal size colored paper.
• A rubric is attached to make sure you know what is expected.
Zacharias Jansen was
said to have made the
first compound
microscope by putting 2
convex lenses in a tube.
Matthias Schleiden,
a botanist,
concluded that all
plants are made of
cells. Helped
develop a part of the
cell theory, which
states that All living
things are
composed of cells;
cells are the basic
unit of structure
and function in
living things.
Robert Hooke created the term
“cell” after looking at cork
under a microscope because
they reminded him of small
rooms in monasteries and jails.

German biologist
Rudolf Virchow
supplied the
third part of the
cell theory when
he stated that all
cells come from
the division of
preexisting cells.

Dutch scientist Anton van
Leeuwenhoek developed a simple
light microscopes to observe living
organisms. Also viewed his own
dental scraping and called them
“animalcules”

Theodor Schwann, a
zoologist, concluded that
all animals are made of
cells. Helped develop a
part of the cell theory,
which states that All living
things are composed of
cells; cells are the basic
unit of structure and
function in living things.
