5 Study Guide
We will take Quiz 5 on Wednesday, Sept. 24. I
recommend that you answer these questions yourself or with classmates.
This not a graded assignment, nothing is to be turned in. These
questions are just to help you prepare for this quiz.
Reading: You should read Chapter 4 in the text book on Cell Structure.
Also, this quiz will cover some material from Lab 5 as indicated in the
questions below.
There are flashcards and animations on the Aris site you should study.
