Name________________________ Mitosis Internet Review: http://www.cellsalive.com On the left side of the screen is a navigation bar, click on the link that says “mitosis”. Read the text on the bottom of this page to answer the questions below. 1. Which stage does the following occur? a. Chromatin condenses into chromosomes___________________________ b. Chromosomes align in the center of the cell__________________________ c. Longest part of the cell cycle________________________________ d. Nuclear envelope breaks down___________________________________ e. Cell is cleaved into two new daughter cells__________________________ f. Daughter chromosomes arrive at the poles__________________________ 2. Now watch the video on this link. You can slow down the video by clicking step by step through the process. (HINT: the colored chromosomes represent chromatids- there are two of each color because one is an exact duplicate of the other), a. How many chromosomes are visible at the beginning of mitosis?________________ b. How many are in each daughter cell at the end of mitosis?______________________ c. The little green shaped T things on the cell are______________________________ d. What happens to the centrioles during mitosis?_____________________________ 3. Now go to the following link: http://www.biology.arizona.edu/cell_bio/activities/cell_cycle/cell_cycle.html Read through the introduction then click the “next” button. This will happen three times. Now you will be given a “cell” and have to classify into one of the following stages. Complete the chart below, keeping track of each cell that you classify. Interphase Number of Cells Percent of Cells (number of cells/ 36 times 100) Prophase Metaphase Anaphase Telophase Total 36 100% 4. Draw cells at each phase of mitosis. Label the chromosomes and other visible structures.
