STATION ONE – MITOSIS MEMORY Have you ever played the game “Memory?” In this game, you must match the illustration of a somatic cell undergoing the cell cycle to its description of what is occurring during that phase. But keep an eye out, someone else just might flip over the card you need! Flip all cards over (face down) in four rows of six. The oldest team member will start the game by flipping over two cards. A pair of cards can only be “collected” if the picture of the cell matches the phase description. Proceed clockwise around the table with each person turning only two cards at a time. If you collect a pair, your turn continues. The team member who collects the most cards wins! Good luck! 1 2 3 4 6 5 -A- -B- Sister chromatids are pulled apart by the shortening of the spindle fibers towards the opposite ends of the cell. Anaphase. The cell is carrying out normal metabolic functions. DNA is replicated during this phase. Interphase. -C- -D- The cell continues to pull apart. The nuclear envelope reappears and the chromosomes uncoil back. Telophase. The nuclear membrane dissolves. Chromatin condenses into chromosomes. The spindle fibers begin forming from the centrioles. Prophase. -E- -F- The cells completely divide due to the division of the cytoplasm. Cleavage furrow develops in animal cells. A cell plate forms in plant cells. Cytokinesis. The chromosomes line up along the equator of the cell. Spindle fibers attach to the centromere. Metaphase. Answer Key for Mitosis Memory: Picture 1 pairs with description F Picture 2 pairs with description B Picture 3 pairs with description D Picture 4 pairs with description A Picture 5 pairs with description C Picture 6 pairs with description E STATION TWO – CELL CYCLE VOCAB CHALLENGE Split your team into two groups. Each group will be competing against the other. Work quickly and diligently! Flip all cards over (face down) from your team’s packet. The youngest team member will say “GO” to begin the game. Flip over your cards and place the description phrases next to the appropriate vocabulary term. Once both teams are done, check your answers against the answer key. The team with the most correct pairings wins! Good luck! Cell Cycle A series of events in which cells continuously grow and divide. 1 Q Interphase 2 Cell Division (Mitosis) 3 Cytokinesis 4 Chromosomes 5 Chromatin 6 The stage during which the cell grows, carries out normal functions, and replicates the DNA. P The stage of the cell cycle during which the cell’s nucleus and nuclear material divide. O The method by which a cell’s cytoplasm divides, creating a new cell. N Made up of DNA. Carriers of genetic information. Made up of two chromatids held together by a centromere. M Long winding strands of DNA. L Chromatid 7 The two structures which are held together by a centromere to form a chromosome. K Cyclin Protein which binds to enzymes and regulates the cell cycle. 8 J Cleavage Furrow Develops during cytokinesis of an animal cell due to the pinching in 9 of the cell membrane. Cell Plate Develops during cytokinesis between plant cells. 10 H Cancer Uncontrolled growth and division of cells. G 11 Carcinogen 12 I A substance which is known to cause cancer. F Apoptosis Programmed cell death. 13 E Homologous Chromosomes Two paired chromosomes, 14 one from each parent. Gamete 15 Meiosis 16 Crossing Over 17 D Haploid cells produced by meiosis. Contain 23 chromosomes in human cells. C Necessary for sexual reproduction. Process which results in the production of gametes. B Occurs during Prophase I of Meiosis. Genetic information is exchanged between homologous chromosomes.

Each team member is competing individually. Flip all cards over from your team’s packet. Each person will need a copy of the Mitosis vs. Meiosis Venn diagram. The team member whose birthday is closest to today will say “GO” to begin the game. Flip over your cards and place the description phrases in the appropriate location on your venn diagram. Once both teams are done, check your answers against the answer key. The team with the most correct pairings wins! Good luck! MITOSIS MEIOSIS Involves only one cell division Results in two daughter cells Involves two cell divisions Results in four daughter cells Chromosome number reduced from 2n to n Produces new cells Parent cell chromosome number maintained DNA replicates only once Crossing over takes place Necessary for sexual reproduction Results in the formation of gametes Daughter cells genetically different Results in the multiplication of somatic cells Daughter cells genetically identical Asexual reproduction of cells Daughter cells are haploid Occurs in reproductive organs Daughter cells are diploid Occurs in plants and animals Answer Key for station three: Mitosis Meiosis Involves one cell division Involves two cell division Parent cell chromosome number maintained Chromosome number reduced from 2n to n Results in the multiplication of somatic cells Crossing over takes place Asexual reproduction of cells Results in the formation of gametes Results in two daughter cells Occurs in reproductive organs Daughter cells genetically identical Results in four daughter cells Daughter cells are diploid Necessary for sexual reproduction Daughter cells genetically different Daughter cells are haploid Both Occurs in plants and animals Produces new cells DNA replicates only once STATION FOUR – OH MY (OSIS)! You and a partner will work together to use a variety of materials in order to illustrate the stages of meiosis i and meiosis ii. Review the materials available to you for cell-building. First, you will need to determine which materials you will use to represent the following: cell, nucleus, chromosome, spindle fiber, centriole. Start by building a cell which illustrates Prophase I of Meiosis I. (Use the pictures as a guide) Have your teacher check each stage before you move on to the next one. The final stage you and your partner should have checked off is Telophase II of Meiosis II (where you should have four haploid daughter cells!). STATION FIVE – IT’S CELLTASTIC! You may work together on the crossword, but you are responsible for completing your own sheet. Turn to the crossword puzzle on the back of your study guide. Work with your partners to figure out and fill in the answers of your crossword puzzle. Keep in mind, this puzzle contains information for both Mitosis and Meiosis. If you finish early at ANY other station, you may continue working on your crossword puzzle. Hint hint: this will be a very helpful study tool for Friday’s test! Finally, have your teacher check your crossword puzzle against her key. STATION SIX – A RADICAL REVIEW! You may work together on the study guide, but you are responsible for completing your own sheet. You will need a separate sheet of paper for this station. Turn to the study guide you were given in class. Work with your partners to review the information laid out in the study guide. Use the study guide as a checklist. Check off the terms and/or items you know well and keep a separate sheet of paper with information you need to further review. Hint hint: this will be a very helpful study tool for Friday’s test!
