What theory did these scientists provide evidence for?

• Modern Cell Theory

What instrument was necessary before the cell theory could be developed?

• The Microscope

Which 3 scientists directly contributed evidence for the cell theory?

• Matthias Schleiden, Theodor Schwann, and Rudolph Virchow

How did the earlier scientists and their contributions directly affect the discoveries of later scientists?  (What came first)

• The creation of the microscope by the Janssens allowed for the observation of microorganisms.
• Leeuwenhoek's lens for the compound microscope allowed for higher magnification power.
•  Hooke put a name to the 'boxes' (cells) which are later considered the basic unit of life.  

List the 3 parts of the original Cell Theory.

• Cell is the basic unit of structure, physiology, and organization of living things
• Cell retains dual existence as distinct entity and building block
• Cells form by free-cell formation

What are the six tenets of the modern Cell Theory?

• All known living things are made up of cells
• The cell is the structural and functional unit of all living things.
• All cells come from pre-existing cells by cell division
• Cells contain hereditary information which is passed from cell to cell during cell division
• All cells are basically same in chemical composition
• All energy flow of life reoccurs within cells

Hooke observed a slice of cork and found it to be composed of small structures that he later named "cells".]]> 2021-01-27 19:24:08 UTC https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133443996 tcurtis41 https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133451630 Anton van Leeuwenhoek
Leeuwenhoek created a higher magnification for the compound microscope and was the first to record his observations of various microorganisms. ]]> 2021-01-27 19:25:37 UTC https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133451630 tcurtis41 https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133458546 Matthias Schleiden
Schleiden concludes that all plants are composed of cells; he is also a cofounder of cell theory.]]> 2021-01-27 19:27:02 UTC https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133458546 tcurtis41 https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133463111 Theodor Schwann
Schwann concludes that animals are composed of cells, is the first to publicly conclude that all living things are made of cells, and is a cofounder of the cell theory. ]]> 2021-01-27 19:27:57 UTC https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133463111 tcurtis41 https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133469876 Rudolph Virchow
Virchow concluded that cells arise from pre-existing cells via cell division; he is also considered a cofounder of cell theory. ]]> 2021-01-27 19:29:20 UTC https://padlet.com/tcurtis41/x0q2pa0j1ouxhinr/wish/1133469876
