General Biology Lab II

13 - Phyla Platyhelminthes and Nematoda

In this lab exercise, you observed the wide diversity of animals in the phyla Platyhelminthes and Nematoda. You will be expected to recognize each group and their distinguishing characteristics. Consult your lab manual for the role of each in its environment, the structures that you will need to recognize on each specimen, and their functions.  Pay attention to which are parasites and which are free-living. As in all exercises, concentrate on those structures in bold face type and those that you were asked to label on your diagrams.
