You must be able to identify all organisms by their common names (not provided on wordbank). You must be able to select from a wordbank the correct lifestyle, classification, and any specific structure indicated. You must be able to give the function of the specific structures and list a distinguishing characteristic of the groups of organisms studied. Know how the representative organisms reproduce.
