Lab 3A. 1. Observe prepared slides of whitefish blastula and onion root tips under the 10X and 40X objectives. Sketch and identify each section of cell division. Lab 3A. 2. Observe every cell and determine what stage the cell is in. Count at least 200 cells total, separating them into groups of the same phase.stain on you!) While looking at the root tip under a microscope, poke and tap at the root tip in the stain to make the cells of the root tip fall apart. 2. Do this sort of thing for about five minutes. Take time to make sure the root tip is really fragmented into tiny pieces. Add a little more stain if your root-tip starts to dry out. 3.Determining time spent in different phases of the cell cycle. In telophase, the sister chromatids have been pulled to opposite sides of the cell and the nuclear membrane forms around each new nucleus. In this cell, although the chromosomes appear to be organizing on a single line. Try again. Vocabulary.Cell Cycle Lab Report Instructions: For this lab activity, you will examine a section of an onion root tip under a compound light microscope to determine the approximate amount of time spent in each stage of a cell's life cycle. At the end of your lab activity, you will complete chi-square testing using some of your data. Submit your lab report to your instructor when completed.Cell Growth and Division - Onion Root Tip Mitosis Lab (Higher Level) Created by. Dan the Bio and Chem Man. The lab is used to view a prepared slide of an onion root tip to see cells in the phases of mitosis. The root tip slides always have cells in interphase, prophase, metaphase, anaphase, and telophase, with the bulk being in interphase.Locate the meristematic tissue to observe phases of mitosis using high power. Find each phase of mitosis on the slide. As you locate each phase, your instructor will verify that you are correct and initial your paper. After you have received verification from your instructor, draw the cell in Table 1. Figure 5. Mitosis in the onion root tipInstructions: The Virtual Cell Division Lab is on the lesson assessment page. On the image, it says "Click Anywhere to Start." Follow the instructions as you move through the lab. The lab activity will keep count of your data on the right, and you can record this into the data table.

It is followed by division of the cytoplasm known as cytokinesis. Both mitosis and cytokinesis are parts of the life of a cell called the Cell Cycle. Most of the life of a cell is spent in a non-dividing phase called Interphase. Interphase includes G1 stage in which the newly divided cells grow in size ...The lab is used to view a prepared slide of an onion root tip to see cells in the phases of mitosis. The root tip slides always have cells in interphase, prophase, metaphase, anaphase, and telophase, with the bulk being in interphase. The students can analyze the slide to see how many cells in a given view are in each phase of mitosis and the ... Constant: The microscope used to magnify the onion root tip, the slide the root is placed on stays the same, the day its magnified Procedure: 1. Obtain a slide of onion root cells. Examine the slide under the microscope using the low-power lens, then focus on high power. 2. Find examples of cells in each stage of the cell cycle, including ...4. Place the vial containing root tips in acetic orcein in the 55 °C water bath for 5 minutes to intensify the staining. 5. After 5 minutes, use forceps to take the tips out of the vial, and place them on a microscope slide. Add a drop of water to the root tip on the slide. Tease the root tip apart with needlestotal time for mitosis in onion root tip cells is 720 minutes (12 hours). Therefore, to calculate the time for each stage of mitosis in these onion cell, set up a ratio of the number of cells in each phase, compared to the total number ofOnion Root Tip Lab Watch this EdPuzzle video on Mitosis: Mitosis Video For reference, here is what is happening in each mitotic phase. DESCRIPTION OF MITOTIC PHASES Interphase Prophase Metaphase Anaphase Telophase Image Description Cell carries out normal functions and is NOT actively dividing. DNA condenses into chromosomes. Chromosomes line up along the middle of the cell.They use onion root tip because growth roots occurs at the tips, where cell will most actively undergo mitosis then sketch each stages as what you saw in the root tip of the onion. And after identifying the four stages, next part is calculating the approximate time it takes for a cell to pass through each of the four stages using the given formula.
