Lesson 1: Phytoplankton Microscopy Lab
Instructions: Look at Slides 1–6 in the
SLIDES – Lesson 1: Phytoplankton Microscopy Lab. Draw and identify as many
organisms as you can on the slides by using the PHYTOPLANKTON ID GUIDE – Lesson 1: Phytoplankton Microscopy
Lab, and then describe key features in Table 1.1. Number each organism in your drawing with its corresponding number
from Table 1.1. An example is shown for Chaetoceros.
