Rachel and Caitlin's Experiment: Hold Me Closer, Tiny Membrane
Hypothesis: There is no relationship between the size of an organism and the size of a cell, but rather, the amount of cells.
We tested our hypothesis by looking at various specimen and measuring the cells within each specimen. Here are our results:
1. Pinus-cells varied in size, with larger cells clustered in the middle. The cells generally ranged from 10-40 microns.
2. Coleus- no observable pattern of cell grouping. Average cell size was 30 microns.
3. Buttercup root- rounder cells ranging in size from 30-50 microns.
4. Carolina- clumps of cells ranging from 40-50 microns
5. Pig intestine- average cell was about 5 microns.
From this data, we have concluded that our story is a good one. There seems to be no observable relationship between cell size and organism size. Each sample had cells of many different shapes and sizes. This diversity at the smaller scale perhaps reflects the diversity that we see in species as a whole. However the reason for this will require further inquiry through observation, research, testing, questioning.
