<p>So which topics did your teacher emphasize so many times during his/her lecture, saying "I would be surprised if THIS wasn't on the exam." I'm in the process of reviewing for the AP exam, but I just want to touch on the most important concepts with only 10 days left. </p>
<p>To be fair, I guess I'll go first: Plant hormones</p>
<p>An obvious one: the cell membrane</p>
<p>@Islander4 - my teacher skipped over animal physiology…nearly completely. Thank god for Cliff’s! I have only the Lab reviews, ecology, and another topic left to review.</p>
<p>Whoops. I misread the first post. Anyhow, I’ll say animal taxonomy.</p>
<p>According to the Cliff’s book, these are what they call “must-know essay questions” since they appear so frequently and are so fundamental:</p>
<p>Cells (structure, and the membrane)
Respiration
Photosynthesis
Cell division
Molecular genetics: DNA structure, replication, protein synthesis
Evolution: Natural selection, speciation
Plants: reproduction in flowering plants, plant tropisms and hormones (especially auxin)
Animal structure and function: nerve transmission, muscle contraction
Ecology: Succession, biogeochemical cycles.</p>
<p>Photosynthesis, Cellular Respiration, Molecular Genetics, Nerve Transmission, Mitosis & Meiosis, Evolution, Plant Structure (especially seeds) have all been focused on in the 3 AP Bio exams I’ve taken, and my teacher says they’re the most important.</p>
<p>Likewise, my teacher skipped animal physiology. So I’m assuming this topic is not too significant for the AP?</p>
<p>Animal physiology is a highly important topic because it consists of all the body systems. For all intents and purposes, all the topics of an AP subject are important to know for its corresponding exam.</p>
<p>There is an outline on the College Board website that will tell you approximately what percent of the exam is made up of each subject.</p>
