Cell Observation

Submitted by PS2007 on Wed, 09/26/2007 - 1:58pm.

Before we looked at cells under a microscope we hypothesized that the larger organisms would have larger cells. We looked at the cells of a Buttercup root, a pig cell, a Pine stem, a Coleus stem tip, and a shark brain cell.

By looking through the microscope we found that the Buttercup root cell was on average 30 microns across. The Pig cell was on average 7 microns across. The Pine stem cells averaged 25 microns across. The Coleus stem tip cell averaged 50 microns across. The Shark brain cells had a lot of variety, with many cells differing in shape and size. They were very small, on average 3 microns across.

Through our observations we found that the size of the cell is not proportionate to the size of the organism it comes from. We did not see a pattern in the cells that we examined but we would interested in examining more cells and trying to discover one. The shark brain cell really piqued our curiosity. It made us wonder if different parts of an organism have different kinds of cells.
