Click on the following links to view images of slides (microscope or 35mm), movies, or dissections encountered in the lab.

Test yourself by identifying the features labelled by arrows in these images. Can you name the higher taxonomic group to which each organism belongs? If not, use the key (for easiest use, hold the cursor down on the "key" link until you see the option "New Window with this Link"; this will open a second browser and allow you to view the key and the study image at the same time).
