Cell Theory History
This invention allowed scientists to discover and learn about cells.
Microscope
True or False: Cell Theory was developed by one scientist.
False!
In your own words, define MULTICELLULAR.
Made of many cells.
In your own words, what is observation?
Gathering info about the world using your five senses.
This word, coined in 1665, means "small room" like the dorm rooms monks lived in.
Cell
In your own words, what is Principle 1 of cell theory?
All living things are made of cells.
Getting larger and more complex over time.
Growth and Development
In your own words, what is an inference?
A guess based on observation. A claim made with evidence.
Name the scientist who made up the term "cell" while looking at a slice of cork wood in 1665.
Robert Hooke
In your own words, what is Principle 2 of cell theory?
Cells are the basic unit of structure & function in living things.
DAILY DOUBLE
For 300 points each, you have 30 seconds to name as many internal stimuli as you can.
Thirsty, hungry, needing the bathroom, tired, nauseated, sleepy.
Small unicellular organisms that live in pond water.
Name a scientist who helped invent the microscope.
Zacharias Jaansen, Anton van Leeuwenhoek, Galileo Galilei, Robert Hooke

All cells come from pre-existing cells.
This type of reproduction means an organism has only one parent. The offspring has the same DNA as the parent.
Asexual Reproduction
Amygdala (safety; fight, flight or freeze)
Prefrontal Cortex (thinking and learning).
Name a scientist who helped develop Cell Theory.
Anton van Leeuwenhoek, Robert Hooke, Rudolph Virchow, Theodor Schwann, Matthias Schleiden, Robert Remak
In your own words, why is it called "Cell Theory" and not "The Law of Cells"?
It is impossible to prove. It is an inference based on a lot of observation.
This word means maintaining stable internal conditions such as body temperature, water level, nutrient level, etc.
Homeostasis
This is the name Anton van Leeuwenhoek made up to describe the living unicellular organisms in his teeth scrapings. It means "little animals."
