Hello Robert Brown! What are these devices on the table? I've never seen anything like it before!
Well citizen, these are microscopes. Would you like me to tell you about them?
Using these microscopes, I was able to discover the nucleus inside cells 2 years ago in 1828.
These are compound light microscopes. They allow you to look at things 1500x closer by using a series of lenses to magnify objects.
Nucleus? Cells? What is that?
Let me explain something to you called the Cell Theory. There are three parts.
1. All organisms are made of one or more cells. 2. Cells are the basic units of organization in organisms 3. All cells come from preexisting cells
Wow! I'm learning so much! Cells sound so important!
That they are, sir.
