Once upon a time there was a very intelligent (and crazy) scientist named Robert Hooke. Hooke was an English philosopher who founded and named cells.
Look at these little dancing things. They look like they are having a party! I will call them cells because they look like the small cells monks live in.
A little while later, there was another scientist named Robert. Robert Brown. Brown, who was a botanist, heard about these cells and was very interested. He decided to do a little more research....
I can see cells with little dots in them in these plants! I will call the dots a nucleus
With cells and nucleuses in mind, a german scientist named Matthias Schleiden co-founded the Cell Theory and decided that all plant tissues were made up of cells. He made groundbreaking discoveries about the nucleus
Wow, the nucleus really is an important part of cells. I shall write all about them
