List the stages of mitosis 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 ___________________________________ 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 centrioles. What happens to the centrioles during mitosis? Meiosis Tutorial  HYPERLINK http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/main.html http://www.biology.arizona.edu/cell_bio/tutorials/meiosis/main.html If your computer does not play the animation, try  HYPERLINK http://www.lewport.wnyric.org/jwanamaker/animations/meiosis.html http://www.lewport.wnyric.org/jwanamaker/animations/meiosis.html See the Contents: You will browse through each topic.  Give an example of asexual reproduction. What is a clone? Name the two types of gametes produced by meiosis. (click the next button)  What is the diploid chromosome number for humans? 5. Egg and sperm cells are [ haploid / diploid ] (click the next button)  Name the stage of meiosis 1 where each of the following occurs: Homologous chromosomes pair and form synapses _____________________________ Bivalents align at metaphase plate _____________________________ Two complete daughter cells form _____________________________ Nuclear membrane disappears _____________________________ Nuclear membrane reforms _____________________________ Chromosomes move to separate poles _____________________________  At the end of meiosis 2, each cell contains how many chromosomes? (click the next button)  Name 2 errors that can occur during meiosis.

Go to  HYPERLINK http://www.calculator.com www.calculator.com and click on the fractions calculator. 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.
