Mitosis Tutorial

http://www.cellsalive.com/

Go to the “Interactive Eukaryote Cell Cycle” and click on MITOSIS. Click on “Start the Animation”. Use the right side links to click through the phases of the cell cycle.

1. Which stage does the following occur:

Chromatin condenses into chromosomes.
Chromosomes align in center of cell.
Longest part of the cell cycle.
Nuclear envelope breaks down.
Cell is cleaved into two new daughter cells.
Daughter chromosomes arrive at the poles.
Chromatids are pulled apart

2. Watch the video carefully. The colored chromosomes represent chromatids. There are two of each color because one is an exact duplicate of the other.

How many chromosomes are visible at the beginning of mitosis? ________________
How many are in each daughter cell at the end of mitosis? __________________
The little green T shaped things on the cell are: ____________________________
What happens to the centrioles during mitosis? _____________________________

3. Identify the stages of these cells and label the structures shown.

Onion Root Tip

http://www.biology.arizona.edu/cell_bio/activities/cell_cycle/cell_cycle.html

Read the introduction, then click the “next” button.

You will have 36 cells to classify. When finished, record data in the chart below. Round to whole numbers.

	Interphase	Prophase	Metaphase	Anaphase	Telophase	Total
Number of Cells
Percent of Cells (calculate: number of cells divided by total cells x 100)

Based on your data, cells spend most of their time in which phase? _________________________________

Mitosis in Whitefish & Onion Roots

http://www.biologycorner.com/projects/mitosis.html

Click on the Whitefish embryo and the onion root tip. For each view, identify the stage of mitosis.

	View 1	View 2	View 3	View 4	View 5
Whitefish
Onion

What are the similarities between the two types of cells (onion and whitefish)?

What are the differences?

You Draw It!

Use the space below to draw the four stages of mitosis your own way, be sure to represent the major events of each phase and label structures. You may also use an online program, like sketchtoy.com to draw and share your image.
