In eukaryotic cells, genetic material is contained inside a distinct, membrane-bound nucleus. Plant and animal cells are classified as eukaryotes.

Observe: Click on the cow and observe E. coli under the highest magnification. Notice the microscope magnification is larger for this organism, and notice the scale bar is smaller.

Joelle and Marcus are arguing about the cell structures in living things. Marcus says all cells have the same structures, while Joelle says that some cells have different structures. They each want to prove they are right. Andre’ was tired of listening to them argue and told them they needed to “prove it”.

In the Cell Types Gizmo, you will use a light microscope to compare and contrast different samples. On the LANDSCAPE tab, click on the Elodea leaf. (Turn on Show all samples if you can’t find it.) Switch to the MICROSCOPE tab to observe the sample as it would appear under the microscope. By default, this microscope is using 40x magnification.

Drag the Coarse focus slider until the sample is focused as well as possible. Then, improve the focus with the Fine focus slider. Select the 400x magnification. If necessary, adjust the fine focus. The individual chambers you see are cells, the smallest functional unit of an organism. Click on the show labels button.
