3.1 PowerPoint Fill In Notes Cell Theory
KEY CONCEPT: Cells are the Basic unit of life.
The cell theory grew out of the work of many scientists and improvements in the microscope.
Anton van Leeuwenhoek
• Known as the Father of _____________________
• Expanded the capabilities of the early microscope and designed over 400 different types of microscopes.
• Studied ______________ water and the unseen organisms that live in the water.
MICROSCOPE INVENTED/ BEGINNINGS OF MICROSCOPE
•
•
•
Around _______________ the microscope was invented.
This microscope belonged to Robert ______________ and was used in 1663.
He looked at a sliver of cork under a microscope. He saw empty spaces and called them “____________”.
CELLS ARE THE BASIC UNIT OF LIFE
•
•
•
Cells are the basic unit of structure and function of living things.
This means that cells:
 Make up all _________________ things.
 Provide instructions for what the organism is supposed “___________________”.
 Provides the outline for what the organism is supposed “___________________________”.
Matthias Schleiden and Theodor Schwann began the cell theory in 1838 by stating:
 All living things are composed of ________________
 Cells are the _________________ ________________ of structure and function in living things
Rudolf Virchow added to the theory in 1855 by stating:
 All cells are produced from ________________ _____________________.
THE CELL THEORY HAS 3 PRINCIPLES.
