Developmental Biology BIO 442 CHAPTER 3 TERMS TO KNOW The following terms are freely used in your textbook. Make sure you know what they mean, how they are used, and how to use them. When an example is given, make sure you can describe and recall it. If a picture is provided, know what the structure looks like and where it is located. If a diagram describes an experiment, make sure you understand the experiment by being able to describe it in your own words. It is often helpful to look in other chapters of the book to gain a thorough understanding of how the terms are used. Although some terms may not be mentioned in class, as a student of developmental biology you are still responsible for understanding them. Do explore Vade Mecum and the Web sites.
