1 LAB PRACTICE QUESTIONS Disclaimer: These questions are only for extra practice and are suggested only by your UGSI who does not take part in writing any part of the actual lab exam. Slides belong to Bio1A. Remember(!!) that there are actual dissections/setups at stations on the real exam (do not rely on pictures alone!!). The actual test will be 75 pts in 27 question stations. The practice test here does not necessarily represent 75 pts. The point values of the questions here would vary in value depending upon the complexity of the question and the answer. Questions 1-4 below would be one station in the exam with 4 parts. 1. Is this organism monoecious or dioecious? (1) 2. What Phylum does this organism belong to? (1) 3.
