My name is Billy. I need to study for my cell test tomorrow! I don't know what to do!
I can help you, I am a cell expert. I will teach you about the Cell theory, and the awesome people who created it. Let's go and explore places you can find cells.
My backyard? Where can I find cells here?
You see Billy, the first rule in the cell theory is that all living things are made up of cells, like that tree right there. And if you were wondering, a German botanist named Matthias Schleiden discovered that all plants are made of cells in 1838. Lets go to another place.
At this school you will see a lot of children. They are all made up of cells too because humans are animals. Theodor Schwan discovered that all animals are made up of cells too!
Interesting... But where do the cells come from?
Good question. All new cells are formed from other existing cells, another principle of the Cell theory! It was Rudolph Virchow, a German scientist, who first stated this in 1858. Now we can go back.
Thanks random stranger guy!
There's one last part of the Cell theory that I forgot. It's that cells are the basic unit of structure and function. So therefore cells are very important. By the way, Robert Hooke was the English scientist who came up with the name cells after looking at cork under a microscope. Don't forget that and good luck with your test!
I got a 100% on my cell test!
Remember, the cell theory says that cells are the basic unit of structure and function, that all living things are made of cells, and that all new cells are formed from other existing cells.
