  1. Cells and Chromosomes Tin Tin Su University of Colorado Meads Elementary school visit Feb 22, 2010 uhaweb.hartford.edu/ BUGL/RBCs.jpg

  2. Nathan Sawaya All living things are made of cells missinglink.ucsf.edu Like blue Lego Man is made of lots of little blue Lego pieces uhaweb.hartford.edu/ BUGL/RBCs.jpg

  3. plants are made of plant cells www.microview.org.uk dogs are made of dog cells www.justusdogs.com.au publications.nigms.nih.gov Fruit flies are made of fruit fly cells iml.jou.ufl.edu bio.research.ucsc.edu/people/sullivan/

  4. If you look inside each cell, you will find chromosomes http://upload.wikimedia.org/wikipedia/commons/thumb/d/df/Drosophila_metaphase_chromosomes.jpg/800px-Drosophila_metaphase_chromosomes.jpg

  5. Cells in female flies have 2 X chromosomes Cells in male flies have one X and one Y (plus a lot of other chromosomes) public.bay.livefilestore.com

  6. X chromosome en.wikipedia.org Mr. Thomas Morgan studied a white eye fruit fly. It was a male. He figured out that it had white eyes because it had a different X chromosome. Fly pictures from: course1.winona.edu

  7. Chromosomes carry instructions for what cells in your body make or do (like your eye color or proteins to fight off germs) www.genome.gov

  8. When you grow, you need to make more cells copy Line up split How to make more cells: Take a cell, copy everything in it, split into two

  9. When you grow, you need to make more cells How to make more cells: Take a cell, copy everything in it, split into two

  10. Make sure each cell gets a set of chromosomes From Foley and Sprenger, 2001

  11. Little protein machines push and pull chromosome copies

  12. ABNORMAL NORMAL dms.dartmouth.edu When things go wrong….. When cells lose chromosomes, they lose information, and can cause diseases like cancer

  13. ABNORMAL NORMAL dms.dartmouth.edu Become a scientist, so you can figure out what goes wrong and fix it!

  14. For now, take care of your cells…. Eat well Exercise Sleep to get rest Don’t smoke Wear sun-screen
