MEIOSIS+AND+MITOSIS

Meiosis Worksheet [|POWERPOINT]

Use the links in this worksheet and answer the questions listed.


 * 1) Click here[].
 * 2) Complete the “practice mitosis” and “practice meiosis” exercises
 * 3) In order to separate the chromosomes in half you will have to use the “shift” key
 * 4) How did the results of the two practice exercises differ? (Your own words)
 * 5) Click here []
 * 6) How many steps to complete Mitosis?Meiosis?
 * 7) Go to the last step in Meiosis. What does it say about “daughter cells” ?
 * 8) []What does it say in number 3 “New allele combinations”, about crossing over?
 * 9) Recently in the media news there has been a lot of discussion about “stem cells”. Click here []
 * 10) What is a blastocyst?How many cells does it have?
 * 11) On the next slide what does it say about the potential of stem cells?
 * 12) Where are the cells placed to develop?
 * 13) Look at the last slide. What do they hope these cells can be used for?
 * 14) Here is another [|picture of a blastocyst] the pink cells are the stem cells. Where are they located?
 * 15) This shows you [|how big] it is. Compare to the dime. ([|Here are some real ones]!)

 * 1) Here are some more links you can observe on these topics; ( just for fun)
 * 1) Compare them to what you saw under the microscope
 * 1) [|Meiosis]
 * 2) [|Mitosis]( Click on the video that shows a comparison between Mitosis and Meiosis )Using all we have learned, list at least 3 differences between Meiosis and Mitosis:
