Hypothesis (and how we reached it):

Initially, we tried to come up with a hypothesis without looking at the slides, but Professor Grobstein told us that we should probably at least take a peek. Our hypothesis both before taking a look and after was: the size of an organism's cells is not relative to the size of the organism itself. We observed that while the cell size of each organism varied, never was the cell size relative to the organism's size. For instance, the size of a human uterine size was 250 microns, while the size of a moss cell was 360 microns. A human is a good deal larger than most patches of moss, so in this case, cell size and organism size were not proportional. Below are some of our other findings: (approximates)

Cell sizes in microns

Buttercup cell: 12.5

Uterine cell: 25

Kidney: 24

Pine stem: 28

Fungi: 37.5

Moss: 36

Worm: 8

Algae: 12

Implications:

As our hypothesis was pretty broad, it would have been difficult to disprove it. Our observations were consistent with our hypothesis, but we also discovered that there is too much cell size variation in each organism to form a completely accurate set of observations.
