# 75 Study Guide for Cell Structure/Function Test Name ___________________ This is a summative assessment so study hard-it is worth 50 points! It will go on your progress report. There will be a retake offered for this test for students who score below a 75%; you will be able to bring your score up to 75%. However, in order to be qualify for the retake you must show evidence that you have done the ACTIVE STUDY TECHNIQUES listed below. Before you take the test you will be required to hand in your flash cards, this study guide, and any other evidence of what you did to study for this test. In other words: If you don’t prepare for this test, you will not be able to do the retake if you do poorly! LS 2- Recognize that all organisms are composed of cells. LS 3- Compare and contrast plant and animal cells including major organelles. (cell membrane, cell wall, nucleus, cytoplasm, chloroplasts, mitochondria, vacuoles). LS 4- Recognize that within cells, many of the basic functions of organisms (e.g., extracting energy from food and getting rid of waste) are carried out. The way in which cells function is similar in all living organisms. ACTIVE studying techniques for the Cell Structure and Function Test 1. Reread your text: Chapter 1 Section 2. 2. Go through the following papers in your binder. Highlight the key information I’ve listed: 65. Cell Structure and Function Overview- highlight vocabulary 66. Cell Structure Function Chart: Highlight items with asterisc with a different color- you need to study these more); highlight other cell parts with regular color 67. Plant and Animal Cell Diagrams- all important 68. Homework from textbook: pg 24 1abc, 2abc, 4ab and pg 39 1,2,6,10 Highlight 1c, 2c, 3c 69. Looking Inside Cells: Highlight terms with asteriscs with a different color to study more; highlight other cell parts with regular color. 69a. Formative Assessment: Cell part functions All highlighted 70. Venn Diagram: comparing plant, animal and bacterial cells- all important 71. Bacteria notes: highlight #1-5 72. Relative sizes: highlight diagram including scale and microscopes 3. Make flashcards for the following cell parts in one color: cell wall, cell membrane, cytoplasm, nucleus, chloroplasts, mitochondria, vacuoles. On the front, put the name of the cell part in big letters. On the other side, divide the card into two parts with a vertical line. On the left side, put the important information about its structure. On the right side, write its functions. Your name and section CELL STRUCTURE FUNCTION MEMBRANE Now make flashcards in a different color for the following cell parts: nuclear membrane, nucleolus, chromatin, ribosomes, ER, Golgi body, lysosomes, flagellum. These are the cell parts that won’t be worth as much because they aren’t mentioned on the state frameworks. You should have 15 cards. 4. Put all your flashcards down with the name side up. For each of the following questions, make a pile of the cards that you think answer the question. Check on the back of the cards to see if you are correct. (I’ve put down the number of cards you should have for each question to help you out.) Write your answers in the space provided on the back page. Don’t peek when you practice again! a. Which ones form a boundary of some sort (3) b. Which ones have a role in protein synthesis? (4, or 5 if you think about the genetic code needed) c. Which ones have to do with converting or releasing energy? (2) d. Which ones have a double membrane? (3) e. Which ones are found in animal cells? (13) f. Which ones are found in plant cells? (14) g. Which ones are found in bacterial cells? (6) h. Which ones are found in prokaryotic cells? (6) i. Which ones are found in eukaryotic cells? (13/14) j. Which one is found in plant and bacterial cells but not in animal cells? (1) k. Can you think of any other questions? 5. Make a pile of flashcards found in animal cells. Without looking at the diagram on #67 or your book (so your sketch shouldn’t look just like them), draw an animal cell from scratch using clues from the flashcards if needed. Label it. Then compare it to the one in the book or on #67 to see if you got all the parts. 6. Make a pile of flashcards found in plant cells. Without looking at the diagram on #67 or your book (so your sketch shouldn’t look just like them), draw a plant cell from scratch using clues from the flashcards if needed. Label it. Then compare it to the one in the book or on #67 to see if you got all the parts. 7. Make a pile of flashcards found in a bacterium. Without looking at the diagram on #71 (so your sketch shouldn’t look just like it), draw an bacterium from scratch using clues from the flashcards if needed. Label it. Then compare it to the one on #71 to see if you got all the parts. 8. Get together with a friend. One person reads the characteristics of one of the organelles in the first person singular, one at a time: “I have a double membrane.” After each fact, the other person tries to guess what the cell part is. Make this harder by starting with more general characteristics and then getting more specific. How many clues does it take you to figure out the cell part? 9. Ask a friend or family member to drill you on the stucture (what it looks like) and function (what job does it accomplish for the cell) of cell parts using the flashcards. 10. With a friend, act out the cell parts like we did in the skits. Can you guess what they are? 11. Go online: A. http://www.cellsalive.com/cells/bactcell.htm bacteria cell B. http://www.cellsalive.com/cells/cell_model.htm choose plant and/or animal model to practice; move your cursor over the picture of an organelle to practice C. http://www.cellsalive.com/quiz1.htm take the quiz (you won’t know all of them but you should know some of them D. http://www.cellsalive.com/howbig.htm review relative size with by magnifying items on the head of a pin E. Google: “unlabeled plant cell diagram” and “unlabeled animal cell diagram” and “unlabeled bacteria diagram” to get lots of practice on identifying cell parts. The diagram on the test won’t be the same one as in your notes or book so it’s good to get lots of practice. F. Now Google “labeled animal cell diagram” (and others) to see labeled diagrams 12. Compare the cell to a school. For each cell part listed below, think about its function or job in the cell. Then think of the part of a school that performs that same function or job for the school.
