Mitosis\nRoot lead-in microscope lab\n\nBiology\n\n worry:\nWhat argon the phases of mitosis in a ascendant tip?\n\n hypothesis:\n using a watchful onion plant finalise drop off and a microscope, can you appoint, adjudicate and cypher cells undergoing mitosis?\n\nMETERIALS:\n-Microscope\n-prepared slide of an onion root tip\n\n purpose:\n1. set up a compound light microscope and vacate it ob\n2. place a slide containing an onion root tip under the microscope\n3. turn up the growth zone, which is right above the root at the root tip\n4. focus on low power and therefore switch to medium or high power, use the pictures of the interprets of mitosis to identify the shows on the microscope slide\n5. count the telephone number of cells found in ach storey of mitosis and record it in the data section\n6. prepare the percentage of time individually cell will go across in individually stage of mitosis.\n\n\nDATA:\nStage of mitosis effect of cells % of cells in each stage Number of cells % of cells in each stage Number of cells % of cells in each stage\n\nProphase X 0 X 0 X 0\nMetaphase X 0 X 0 X 0\nAnaphase 20 14 28 17 17 11\nTelophase 13 9 15 9 12 8\nInterphase cv 77 120 74 113 78\nTotal number of cells 138 degree Celsius 163 100 142 100\n\nQUESTIONS:\n1. Of the four stages of mitosis, which one takes the some time to complete?\na. Prophase takes the near time to compete\n2. Which is the shortest stage duration?\na. Metaphase is shortest\n3. What would happen if the impact of mitosis skipped metaphase? Telophase?\na. Then they would non discriminate correctly\n4. Why do you think cells were dividing only at the root tip?\na. center\n5. Three reasons cells must set apart?\na. To have enough cells\nb. To set back old cells\nc. To maintain protrude area\n6. Why is Interphase not considered part of mitosis?\na. Because there is technically no genetic movement.\n7. watch:\na. Spindle fiber: caboodle of microtubules that span the cell heart and soul\nb. Centriole: small structure in animal cells that helps to organize microtubules\nc. Chromatid: strands of chromosomes that breathe in identical pairs\nd. chromatin: material of chromosomes that consists of DNA and proteins\ne. centromere: the part of a chromosome where choromotids are attached\n\nCONCLUSION:\nUsing a prepared onion root slide and a microscope, identification was confirmed, and cells undergoing mitosis were able to be counted and categorized.If you want to get a full essay, order it on our website:
