  1. 4. Condensed Chromatin (DNA and Proteins) are shaped like an X. O
  2. 6. Egg and Sperm E
  3. 8. cells: Produce gametes and are the only cells that can undergo meiosis as well as mitosis. C
  4. 10. Cells: 2 new cells as a result of cell division. N
  5. 11. Chromosomes line up in the middle of the cell and line up at the equator.
  6. 13. (2n): When egg and sperm combine G
  7. 17. series of changes in the Nuclei of body cells that produce identical Daughter cells. L
  8. 18. Fibers: Green Strings within Anaphase/ pulling towards opposite poles of the cell. F
  9. 19. Two sister chromatids join together to form 1 chromosome. M
  10. 20. Cycle: series of stages where cells change as they grow and divide to create 2 new cells. A

  1. 1. Chromosomes separate and move to opposite poles of the cell.
  2. 2. Process by which 1 diploid (2n) splits over 2 stages to become 4 Gamete/ Daughter Cells. K
  3. 3. Nuclear membrane forms around each set of chromosomes forming 2 nuclei.
  4. 4. Division: Complex series of changes in the nucleus of a cell that leads to the production of 2 new cells. H
  5. 5. life process in which living things produce other living things of the same species.
  6. 7. An organelle near the nucleus of a cell which contains the centrioles (in animal cells) and from which the spindle fibers develop in cell division. B
  7. 9. (n): ½ the number of chromosomes J
  8. 12. Increased cell size and DNA replication
  9. 14. Separation into 2 identical daughter cells.
  10. 15. Double Stranded Chromosomes become visible and the nuclear membrane disappears.
  11. 16. (2n) When the egg and sperm unite during fertilization. D
