Terms and sample questions for Exam 2.
Each set of notes has a review list at the end of it. Try writing answers to all of the questions given in those lists. In addition to the topics on the list, you should also know important terms. Use the following list to supplement the other lists. The following includes most (hopefully all) of the terms that go with the material covered for your second exam. For many of the terms, it’s not just a matter of being able to define them. You need to be able to describe their role in a process or structure and distinguish between similar terms. Also, some of the terms also appeared on the first exam. This is because the later material in this course builds on the earlier material. These are the terms you still need to know. Your textbook also includes review material at the end of each chapter and at the textbook's website.

| Be able to recognize the parts of a flower in a sketch, such as the one found at
http://arnica.csustan.edu/boty1050/Anthophyta/flower.JPG or in your
textbook. Be able to match specific flower structures/features with pollinators. Know flower features that promote out-crossing. This exam includes two videos: Putting Down Roots and The Birds and the Bees |

The dark, nonfunctional xylem at the center of a tree is called
A. heartwood B. summer wood C.
