cells vs. organisms

Vivian Cruz

Eurie Kim

Hypothesis:
All organisms have same-size cells, but have a different number of cells that determine the size of the organism.

Observations:
Jejunum (pig) - 80 to 90 microns
Cheek cells - 70 to 80 microns
Coleus (stem tip) - 13 to 52 microns
Paramecium Caudatum (protista) - 130 to 182 microns
Pine stem - 13 to 52 microns
Buttercup root - 26 to 78 microns
Ceratium (protista) - 70 to 100 microns

Our story:
From looking at our observations, the smallest organism (protistas) had the biggest cells, the plants (coleus and pine) had the smallest, while the mammals (pig and human) had the middle range-size cells.
This shows that there is no correlation between cell and organism size.
