Our story begins with cells, the things that all living organisms are composed of. Here's a bit of background: cells are the basic unit of structure and function, and cells come from preexisting cells. Let's introduce the scientists who contributed to the Cell Theory.
Hi! I'm Robert Hooke. Have you ever wondered where the term cells came from? Well, you've come to the right place. I was examining a cork under a microscope one day, and I realized the things that made up the cork looked like the rooms that monks live in called cells. I wasn't expecting the name to stick, but it did!
He's not the only famous scientist named Robert! My name is Robert Brown and I am responsible for describing the details of the nucleus of the cell. I also observed the way that microscopic particles move, which is now referred to as Brownian Motion.
Hello! My name is Matthias Schleiden, but you can just call me Matt. I discovered that all plants are composed of cells and declared that cells are the building blocks of all plants, like the ones below me!
Hi, my name is Theodor Shwann. Much like Schleiden, I made the conclusion that all animals are composed of cells. Billions, even trillions of them! Also, the cells in your peripheral nervous system are named after me; Schwann cells.
My name is Rudolf (not the reindeer) Virchow. I was one of the first scientists to accept that cells are formed from preexisting cells. This is a key part of the cell theory!
