Fun with Microscopes

Submitted by paoli.roman on Thu, 09/24/2009 - 2:13pm.

Hypothesis:

"I think the idea that big organisms have large cells and small organisms have small cells is valid."- Paoli

"I think all cells are the same size and that bigger organisms just have more cells."- Laura

Data/ Observations:

We both observed different sizes and shapes of cells. Trying to measure each organism was difficult since we both had different measurements (numbers) on our ruler.

1) Pine Tree-  36.6 microns
2)Laura- 63.3 microns
3) Pig- 7.3 microns
4) Earthworm- 10.6 microns
5) Moss- 7.6 microns
6) Algae- 33.3 microns
7) Fungus- 38.3 microns

We organized our data from largest organism to smallest however the cell sizes did not correlate. Both of our hypothesis were wrong since the size of the organism had nothing to do with the size of its cells and the cells in each organism were different from each other.WE HAD FUN! OUR HAIR IS THICK!
