
Invented the microscope

Viewed cork under the microscope;
assigned the name cells to the “little
rooms” he saw

Thought animals were not made of cells
Anton van Leeuwenhoek
made microscopes
 Looked at pond scum
 Saw protists

Cell Theory

All organisms are made of one or more
cells.

The cell is the basic unit of all living
things.

All cells come from existing cells.

Cell City Analogy
In a far away city called Grant City, the main export and production
product is the steel widget. Everyone in the town has something to do with
steel widget making and the entire town is designed to build and export
widgets. The town hall has the instructions for widget making, widgets
come in all shapes and sizes and any citizen of Grant can get the
instructions and begin making their own widgets. Widgets are generally
produced in small shops around the city, these small shops can be built by
the carpenter's union (whose headquarters are in town hall).
After the widget is constructed, they are placed on special carts which
can deliver the widget anywhere in the city. In order for a widget to be
exported, the carts take the widget to the postal office, where the widgets
are packaged and labeled for export. Sometimes widgets don't turn out
right, and the "rejects" are sent to the scrap yard where they are broken
down for parts or destroyed altogether. The town powers the widget shops
and carts from a hydraulic dam that is in the city. The entire city is enclosed
by a large wooden fence, only the postal trucks (and citizens with proper
passports) are allowed outside the city.
