What Is the Cell Theory?
How do Microscopes Work?
Page 368
What are cells?Cells are the basic units of structure and
function in living things.
Page 369
What is the cell theory?The cell theory is an accepted
explanation of the relationship between cells and living things.
All living things are composed of cellsCells are basic units of
structure and function in living things.All cells are produced from
other cells.Who is this man and what is that object?
Zacharias Jenson 1590sSpectacle MakerPut lenses in a sliding
tube to magnify things,Up to 9x and blurry!Robert Hooke
Robert Hooke built his own microscope and observed slices of
cork from an old oak tree. He described the empty spaces he say as
cells which means small rooms
Antonie Leeuwenhoek
Built microscopes and was the first to see living cells!Page

Schleiden, Schwann, Virchow
All plants are made of cellsAll animals are made of cellsAll
cells come from other cellsPage 371

All living things are composed of cells Cells are the basic
units of structure and function in living things New cells are
produced from existing cells Back then was a guy named Hooke, cut
some cork and he had a look Underneath his microscope tiny rooms
that he saw in groups Empty rooms that looked like shells He's the
one that called them cells Listen up cause we're not done Cell
theory had just begun Add one scientist to know the inventor of the
microscope Anton von Leeuwenhoek saw cells move and he was like
"That's dope" PRE CHORUS Cell theory, cell theory, cell theory,
cell theory, cell theory, go! If you thought this was complete take
a breath and have a seat Two scientists to have their say Schleiden
and Schwann to save the day Schleiden said all plants have cells
they are alive and we can tell The next year Mr. Schwann could see
all animals have cells that live and breathe Oh they live and
breathe Live and breathe In 1855, Rudolph Virchow proposed that all
cells Come from other cells This was the final discovery That ended
