In plants, an area of rapid growth is the tips of roots. This exercise uses onion root tips to illustrate the amount of time spent in each phase of mitosis. Work as a team to look at onion root tips under the microscope. This area of the root is undergoing rapid cell reproduction. If time is short, use the slides below slide 1; slide 2; slide 3Lab 10 Worksheet Answer Key.docx - Activity 1: Mitosis In Plant Cells ... 10. Based on your examination of the onion root tip and your knowledge of the stages of mitosis, please explain whether all observed cells undergoing cell division can be easily assigned to one stage or another. Please provide a logical explanation for your response.Conclusion Questions. 1. The cells in the root of an onion are actively dividing. How might the numbers of cells. found in this region differ from a different part of the plant? - The region behind the root cap of an onion is the mitotic region, which is a site for. rapid growth and thus this explains why the onion's root tip is the fastest ...2. Obtain a prepared slide of an onion root tip (there will be three root tips on a slide). Hold the slide up to the light to see the pointed ends of the root sections. This is the root tip where the cells were actively dividing. (The root tips were freshly sliced into thin sections, then preserved when the slide was prepared.) 3.

Introduction to Biology Lab Estimating Duration of Mitotic Phases Assignment 40 points For this assignment you will write a formal laboratory report about how long each phase of mitosis takes in an onion cell. Mitosis lasts for about 90 minutes in onion root tip cells. Each of the four phases takes a different amount of time.What are the green T shaped things on the cell? Centrioles. Describe what happens to them during mitosis. Move to ends of the cell; pull chromosomes. Label each of the following #1. Prophase. Label each of the following #2. telophase/cytokinesis. Label each of the following #3.BIOSCI-LAB5-MITOSIS &. MEIOSIS. Hypothesis: The cells in onion root tips spend equal amount of time in each stage of cell division. Prediction: If the cells in onion root tips spend equal amount of time in each stage of cell division, then there will be equal percentage of cells in each cell division stage naming interphase, prophase, metaphase, anaphase, and telophase, and cytokinesis.30 jun 2015 ... ... mitosis of onion root tip cells.

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 ... The table below shows the number of cells in different stages of mitosis in a sample from a garlic root tip. Calculate the mitotic index for this tissue (give your answer to 2 decimal places). Mitotic index = number of cells with visible chromosomes ÷ total number of cellsTo test the third hypothesis, we counted the chromosomes of 10 cells during anaphase in the onion root tip. After we took the number of chromosomes and multiplied it to the number of cells it was seen in. To get the average, we divided the total chromosomes seen by the total cells seen. RESULTS The sketches for both the onion and white fish ...

Onion Cell Mitosi s. Background: In a growing plant root, the cells at the tip of the root are co nstantly dividing to allow the. root to grow. Because each cell divides independently of the o thers, a root tip contains cells. at different stages of the cell cycle. This makes a root tip an exc ellent tissue to study the.Download file PDF Read file. Download file PDF. Read file. ...

Type of cell division that results in two identical daughter cells. Interphase. Most time spent in this phase; 3 Stages: G1, S, and G2. Prophase. Chromosomes supercoil and spindle fibers begin to form between centrosomes located at the poles of the cells. The nuclear membrane also disintegrates freeing the chromosomes.The length of the cell cycle in the onion root tip is about 24 hours.
