Schwann Story Board - Atharva Kulkarni
Storyboard Text
- My name is Theodor Schwann, and I'm a professor of anatomy at the University of Berlin.
- I'm currently studying animal tissues. They're made of these little glob structures, which I've named animal cells.
-
- But my discovery leaves so many questions! Where do these cells come from? Are they unique to animals?
- Ugh...I'm too hungry to deliberate on this. Maybe I'll head out to lunch. I'll even invite my good friend Matthias Schleiden!
- Sure!
- Just finished up and ready to head out on break and...OH HI THEODOR!
- Hey Matthias! I was wondering if you would like to grab a bite to eat!
- Claim: Schwann claimed that all animals were made up of cells.Evidence: Schwann looked at animal tissue under a microscope and noticed glob structures. He noticed that all the cells had a nucleus.Reasoning: The presence of the nucleus in these glob structures established that these structures were in fact cells (validated by Brown’s claim) .
- I'm currently looking at plants under my microscope. I've noticed that my plants are made up of these tiny, rigid, compartments. I've named them plant cells.
- So tell me about your work...
-
- Wait, cells? I thought than only my animal samples had them! And mine look like little globs rather than rigid compartments!
-
-
- Both our samples had a nucleus in them! That means both plants and animals are made of cells?!
- Claim: Schleiden claimed that all plants were made up of cells.Evidence: Schleiden looked at plant tissue under a microscope and noticed rigid, compartment like structures. He noticed that all the cells had a nucleus.Reasoning: The presence of the nucleus in these rigid, compartment structures established that these structures were in fact cells (validated by Brown’s claim).

- Interesting...WAIT! Does that mean...?
- Claim: All life forms are made of cells.Claim: All life forms are made of cellsEvidence: The structures observed in Schleiden’s and Schwann’s respective samples both had a nucleus at their center.Reasoning: Thanks to the work of Robert Brown, both Schwann and Schleiden knew that the nucleus was ubiquitous among all cells. That meant that despite the differences in shape and size, both Schwann and Schleiden’s samples were still made of cells, making the building block for all life.
