PRACTICE QUIZ ON CELL STRUCTURE AND FUNCTION

Instructions: You may prefer to print out the quiz and mark it.  After you have finished marking the quiz, you can grade each question by clicking on a quiz answer.  When you click on a quiz answer, you will be given feedback indicating whether your answer is correct.  When you get a feedback response, click on the back arrow to return to the quiz. After scoring your quiz, you should have an idea if you need to study the material more.  Remember to post questions about things you don't understand in the Class Forum.
