5 - The Protists
In this lab exercise, you observed the wide diversity of protists. Classification of this group has been changing and studying them together is a matter of convenience, not an indication of evolutionary relationships.
Notice the great diversity in this group. Some are autotrophs, some are heterotrophs whose characteristics make them more “animal-like”, others are more “fungus-like” and some cause disease in humans. 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. As in all exercises, concentrate on those structures in bold face type and those that you were asked to label on your diagrams.
