Cell Theory1. All living things are made of cells.2. Cells are the basic units of structure and function in living things. (structure = form; function = purpose)3. All cells come from pre-existing cells.

Taking NotesIn order to complete your timelineTake notes on the following scientistsZacharias and Hans JansenRobert HookeAnton van LeeuwenhoekRobert BrownMatthias SchleidenTheodor SchwannWilliam Henry PerkinRudolph VirchowWrite down their name, date, and a brief description of what they did.

It all started withThe first microscope!Zacharias and Hans Jansen1595Middleburg, HollandPlaced two lenses in a tube

Hans & Zacharias Janssen1595Hans & Zacharias Janssen produced the first compound microscope by lining up 2 lenses.

Robert Hooke1665Robert Hooke observed lining matter (cork cells) through a compound microscope, which reveals empty cells. He is the first to call the spaces in the cork cells which means little rooms.

Anton van Leeuwenhoek1675Anton van Leeuwenhoek observed living cells through a simple microscope. Called the miscro-organisms he saw animacules

Matthias Schleiden1838Matthias Schleiden discovered that plants were made of cells.

Theodor Schwann1839 Theodor Schwann states all animals are made of cells.

William Henry Perkin1856William Henry Perkin develops an intense purple dye, which is used to stain slides.

Rudolph Virchow1858Rudolph Virchow states Cells are the last link in a great chain that forms tissues, organs, systems, and individuals. Where a cell exists, there must have been a preexisting cell.Cells can only arise from pre-existing cells

Create a Cell TimelineLabel the timeline with the dates, scientist names, and details of the important discoveries.The earliest date should be on the left and the most recent on the right.The timeline should represent time as a ruler-like scale so that each cm represents the same number of years.You may use an electronic timeline maker if it takes less time.

Rate the top 5 most significant discoveries on your timeline.

Explain why Number 1 is the most significant
