Quiz 3 – Spring 2006 Study Guide

The topics on this quiz are Lab Ex. 8(seed plants), 10(sponges & cnidaria), 11(worms), and 12(mollusks & echinoderms).

Note: The following questions are a sampling of the types of things you need to know for the quiz.  A good way to prepare is to ask the same questions for all the groups we have looked at in lab, not just the ones listed here. Answers to the study guide questions are listed at the bottom of this page.

2. In what way are the seeds of gymnosperms different from the seeds of angiosperms?

3. a) In what group of plants does “double-fertilization” take place? 
b) Double-fertilization results in a specialized nutritive tissue called the _______________ which is triploid. 

4. Match the following characteristics with the appropriate animal phyla.  Note: each characteristic may be used more than once and each phylum may have more than one characteristic associated with it.

a. bilateral symmetry                           d. cellular level of organization
b. radial symmetry                              e. tissue level of organization
c. no symmetry                                    f. organ/organ system level of organization

______ Porifera                      ______ Cnidaria                     ______ Ctenophora   
______ Platyhelminthes          ______ Nematoda                  ______ Annelida
______ Mollusca                     ______ Echinodermata

7. What does sinistral and dextral refer to?

8. What is the main function of gills?

9. What is the function of the adductor muscles found in the Class Bivalvia?

10. For each of the phyla listed below, indicate whether it is a protostome or deuterostome.
a) Mollusca                  b) Echinodermata                    c) Annelida
