Zacharias Janssen

Robert Hooke
He looked a cork under a microscope and noticed that it was made up by little boxes.He named those boxes ''cells'' because they reminded him of the rooms the monks live in.All those boxes he saw on the cork were dead cells. -
Anton van Leeuwenhoek

Mathias Schleiden
He was the first person to see that plants also have cells in them.He was the first to conlude cells inside all the plants.He saw cells inside the plants by observing plants through a microscope and then saw cells. -
Theodor Schwann
Theodor Schwann discovered that all of the animal tissue is made up of cells.He discovered cels through a microscope.Also Theodor wrote the first two parts of the Cell Theory. -
Rudolf Virchow
Rudolf Virchow was the first to observe that cells come from living cells.He saw cells reproducing from other cells in a microscope.He saw that cells only come from pre-existing cells. -
Invention of the Light Microscope
This microscope is diffrent from other microscope because it uses light and has one more lenses to enlarge things you see.This is one of the early microscopes and it changed lots of ideas of living cells.This microscope was invented by Wilford Thompson. -
Invention of the Electron Microscope
This microscope was invented to enlarge things 100,000 times or more.This microscope can see atoms on or insuface materials.This microscopes can also see structures inside a cell.
