Cell Diversity La
The last two exercise you were introduced to the microscope and the cell. This lab builds off of your knowledge of how to use the microscope, its parts, and functions in order to view your specimens. The cell lab your learned about Plant and Animal cells. You learned about the cellular structure of the cells and were able to compare and contrast their structures and functions.
In this lab your will be examine a variety of cell types, ranging from prokaryotic cells (cyanobacteria and bacteria) to eukaryotic cells (plant cells and animal cells). You should be able to recognize each of these cell types as well as any subcellular structures visible with the light microscopes. In addition, you should be able to name bacterial types and identify Oscillatoria, Anabaena, and Gloeocapsa. Although this is a virtual lab, try to estimate the size of a cell or organism as seen through the microscope. Please review the cell diversity PowerPoint.
Part I:
Please watch the YouTube video at the following links to watch the Oscillatoria and Anabaena (There are also YouTube links in Blackboard).
Oscillatoria: https:

Anabaena: https:

Draw the Oscillatoria and Anabaena at 400X. Label the following on the appropriate specimens (they may overlap): chlorophyll, filament, heterocyst, and individual cell
Oscillatoria (400X)                    Anabaena (400x)                 
Are the cyanobacteria motile? Does their structure influence their motility?
