BOTANY LS1203 - PLANT BIOLOGY - FALL 2009
Terms and sample questions for Exam 1.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 review lists with your notes. The following includes most (hopefully all) of the terms that go with the material covered for your first 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.
