Kingdom: Protista

Introduction

Click here to go to the lecture notes on protists. You may also click on the organism name to view more information about that organism in the notes.

Protists are eukaryotes. As you observe the specimens, notice that the cells are larger and more complex than those of procaryotes.

Kinetoplastids

Trypanosoma is a zooflagellate that causes African sleeping sickness. Observe and draw a prepared slide of Trypanosoma taken from a human blood sample.
