Learning Target: I can evaluate the role of meiosis as it relates to the development of sex cells in the human body. PART B: Meiosis Please go to the following webpage: http://www.cellsalive.com/meiosis.htm 1. Why is the meiosis important? __________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ ____________________________________________________________________________________ 2. Start the animation. What do the chromosomes do in Prophase I? _____________________________ ___________________________________________________________________________________ ___________________________________________________________________________________ __ 3. Compare how chromosomes line up on the equator (for separation) in Metaphase I and II? Include a diagram. ___________________________________________________________________________ ____________________________________________________________________________________

4. In which phase are the number of chromosomes divided in half? _______________________ Is this part of meiosis I or meiosis II? ______________________________ 5. Label the following steps of Meiosis using the image below: #1:_______________________________________ #2:_______________________________________ #3:_______________________________________ #4:_______________________________________ #5:_______________________________________ #6:_______________________________________ #7:_______________________________________

6. How does mitosis and meiosis play a role in the growth and development of the human body?
