Mitosis Internet Lesson Intro Bio
In this internet lesson, you will review the steps of mitosis and meiosis and view video simulations of cell division. You will also view an onion root tip and calculate the percentage of cells at each of the stages of cell division.Mitosis Tutorial
On the left side of the screen is a navigation bar, click on the link to “MITOSIS” Read the text on this page and view the animation, you can slow down the video by clicking step by step through the phases.
1. Which stage does the following occur?
a) Chromatin condenses into chromosomes ______
b) Chromosomes align in the center ______
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. Watch the video carefully. Pay attention to the colored chromosomes, there is a blue, a white, a light blue and a red one.
--How many chromosomes are visible at the beginning of mitosis? ______
-- How many are in each daughter cell at the end of mitosis? ______
-- What happens to the centrioles (green t-shaped objects) during mitosis? ______
3. Identify the stages of these cells:
______
