Mitosis Hands-On labs, Inc. Version 42-0091-00-01 Lab sketch Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiments questions, diagrams if needed, and data tables that should be intercommunicate in a formal lab report. The intent is to facilitate students writing of lab reports by providing this culture in an editable file which can be sent to an instructor.Mitosis Worksheet Answer the questions about the photos below Onion tooth root tip photos at 600x and 1000x taken by Stan Carpenter of Hands-On Labs, Inc. 1. What variety is this electric cell undergoing? Telophase 2. What happens after this phase? Cytokinesis 1. The two pith side-by-side cells ar undergoing two different phases of mitosis. a. What are these phases? Prophase & Metaphase b. What diagnostic features can help you with your conclusion? The cell under going prophase is starting to lose its envelope yet the cell is solace very much intact.General Biology Ii Study Guide (Online Class)The cell under going metaphase has stiletto heel fibers all around the cell suggesting its in the metaphase full stop of mitosis. 1. What phase is this cell undergoing? Anaphase 2. How can you tell? The chromosomes are separated yet not completely in two yet. 1. This cell has clearly visible chromatids. a. Whats the following(a) phase this cell will undergo? Tellophase b. Where will the chromatids go in the coming phase? half(prenominal) the chromosomes go into unmatchable cell and half in the other 1. The cell in the lower center is exhibiting signs of what phase of mitosis? Prophase 2.What phase does it appear the cell above is undergoing? Anaphase 1. Explain what happens during anaphase. The spindle fibers begin to split the chromatids in two. Equal halves of the chromosomes are the result 2. When the chromatids separate, what is each called? Chromosomes Questions A. What is the purpose of mitosis? Produc es the cells in the body as well as DNA. B. Why is the cell cycle important for organisms? The reproduction of cells is essential to the healing of wounds and natural development. C. What role does mitosis suffer in the growth of an embryo? Mitosis creates the embryo.The constant replication of DNA is needed to develop the embryo and it genes. D. What is one main difference in the mitotic processes between plant and animal cells? The main difference is seen in the cytokenisis stage of development. An animal cell will pinch into to form the daughter cells while a plant cell will form a new cell wall to divide the two. E. If the cell that has undergone mitosis originally had the diploid (2n) number of chromosomes, then what number of chromosomes will the nuclei in the two new cells have? 2n F. Can mitosis invariably be used for reproduction?Yes in asexual reproduction G. What parts of plants are most wedged by mitosis? Apical meristem H. Why might mitosis be easier to study in the t ip of the root? Because that is the sector that is most affected during mitosis I. Where else in a plant might you find a large step of mitotic cell division occurring? J. How might the mitotic index be applied in agriculture? K. What did you compute to be the mitotic index of the combined six slides (assume there are 54 total cells)? In comparison to the indexes reflected in Figure 8, from approximately which area of a root was the sample taken?
