Study Guide – Midterm #1 General Biology 103 Approximate Exam Format: Approximate Distribution 25 - multiple choice 10 - matching 10 - labeling on diagrams 20@ ½ pt each 10 - dichotomous choices 5 - short answers (including giving examples) 60 % lecture material – see lecture guides 30 % lab related material - including prelabs 10 % readings from text & articles Suggestions for preparing before the exam: Study a little bit every day (20-30 minutes per night) is much better than trying to cram 3-4 hours the night before the exam. Take frequent breaks from studying. Complete reading of all chapters and notes first! Complete the lecture guide questions, which serve as your first round of “study guide” type questions. Read the chapter review summaries at the back of the chapters (this is a great way to review especially right before the test). Examine the labs & quiz preceding the test including the introductory material. Make sure that you understand all questions and if you missed answering these – then why you missed them? Items to review: Scientific method handout Guppy exercise – exercise to get you thinking about hypothesis building & variables. Plant specific materials: Diagrams used in this unit e.g. parts of a flower, parts of a leaf, whole plant shoots/roots, parts of a seed, stem cross section, root cross section, flowering plant cycle. Review film video guides and/or notes. Review monocot vs. dicot table. Concepts to cover: Note – not all inclusive Cells: What cell structures are unique to plant cells? Where exactly does photosynthesis occur in the cell? What are the cell types that make xylem? phloem? What are guard cells? Tissues: What are the different types of tissues i.e. parenchyma, sclerenchyma, vascular, dermal etc.? What function do each provide for the plant and could explain where they are found in plants? What are meristems? (including their types). Processes: Germination, Fertilization, Meiosis, Mitosis, flow of water into a plant. Photosynthesis, transpiration, pressure flow hypothesis and cohesion-tension theory. How do woody plants add girth to their size? Importance of stomata & their respective role. Nutrients. What factors affect transpiration? Reproduction: What is the difference between the diploid and haploid state? What is a sporophyte? A gametophyte? What is meant by Alternation of Generations? What are the seasonal cycles of plants e.g. annuals, biennials etc and can you give an example of each? Be able to explain double fertilization. Difference between pollination vs fertilization? Other concepts: Categories of fruits (know examples), know the pigments that plants use. What is lignin? Know unique terminology e.g. cotyledons, casparian strip, cambium. Understand the importance of fruit & seeds, including methods of dispersal. Types of flowers that attract pollinators. What is perfect vs. imperfect, regular vs. irregular? What is an inflorescence.
