Mitosis Lab Report




Experiment Mitosis;Lab Report 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 experiment?s questions, diagrams if needed, and data tables;that should be addressed in a formal lab report. The intent is to facilitate student?s writing of lab;reports by providing this information in an editable file which can be sent to an instructor;obseRvations;Mitosis Worksheet - Answer the questions about the photos below;Onion root tip photos at 600X and 1000X taken by Stan Carpenter of Hands-On Labs, Inc.;1. What phase is this cell undergoing?;1. The two center side-by-side cells are;undergoing two different phases of;mitosis.;a. What are these phases?;2. What happens after this phase?;b. What diagnostic features can help;you with your decision?;1. What phase is this cell undergoing?;1. This cell has clearly visible chromatids.;a. What's the next phase this cell will;undergo?;2. How can you tell?;b. Where will the chromatids go in the;coming phase?;1. The cell in the lower center is exhibiting signs 1. Explain what happens during anaphase.;of what phase of mitosis?;2. What phase does it appear the cell above is;2. When the chromatids separate, what is;undergoing?;each called?;Questions;A. What is the purpose of mitosis?;B. Why is the cell cycle important for organisms?;C. What role does mitosis play in the growth of an embryo?;D. What is one main difference in the mitotic processes between plant and animal cells?;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?;F. Can mitosis ever be used for reproduction?;G. What parts of plants are most impacted by mitosis?;H. Why might mitosis be easier to study in the tip of the root?;I. Where else in a plant might you find a large amount 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?
