This storyboard does not have a description.
Robert Hooke, an English scientist, is examining bits of cork under a microscope. What he finds will change the world of science forever.
There appears to be microscopic rooms inside this magnified cork...what could this mean? Perhaps Robert Brown will know!
Robert, I was looking at pieces of cork under a microscope, and I discovered small "rooms" inside it. I do believe I will call them cells, because they remind me much of a prison block. What do you think?
A splendid idea! I have run a few experiments on these cells, and decided that eukaryotic cells must have a central core containing something. That something is the genetic material (DNA) of the cell!
Wonderful! I'll go tell my dear friend Rudolph about our discoveries.
Rudolph, I was looking through my microscope earlier and discovered small "cells" inside a cork! Robert has also found that there is a nucleus inside a cell, but only ones that are eukaryotic.
Wow! Wait a minute! How did those cells get there? They couldn't have just "appeared" out of nowhere. The meat and fly experiment proves that that is impossible...
Later that day, Rudolph and his colleagues, Schwann and Schleiden, are running experiments on the cell.
Every plant is made of cells...
...and that all animals are made of cells!
We have concluded that: Cells only come from preexisting cells
