Botany 130 Exam 1 February 13, 2006 Please give the single best answer for each question. The questions are designed to have only one right answer, or at least one that is much, much better than the alternatives. I have tried to make each question clear. If it looks like a trick question, think about the question some more. None are designed to be tricky but some require thoughtful analysis. Many of the incorrect choices will be phrases you heard in lecture. Read each question carefully. There are 40 questions and seven pages to this exam. ************************ The lines below depict how I described the universal tree of life.
