Across 3. used to produce human tissues; can begin with adult stem cells or embryotic stem cells 5. main microtubule-organizing center of the cell; divides before mitosis begins 6. chromatin is condensed and the chromosomes are visible; nuclear division is about to occur during this stage 8. protein complexes; develop on either side of the centromere during cell division 10. characteristic chromosome number 12. simply newly formed plasma membrane that expands outward until it reaches the old plasma membrane and fuses with its membrane 14. has the appearance of a tangled mass of thin threads; place where DNA is located when a eukaryotic cell does not undergo division 15. daughter cells are forming as nuclear envelopes and nucleoli reappear; chromosomes become chromatin 16. barrel-shaped organelles that come in pairs; found in centrosome of an animal cell ONLY 17. half the diploid number of chromosomes; contains only one chromosome of each kind; usually only found in sperm & eggs 18. indentation of the membrane between the 2 daughter nuclei; forms just as Anaphase draws to a close

Down 1. The production of a new individual 2. location where sister chromatids are constructed and attached to each other 4. array of microtubules that radiate toward the plasma membrane from the centrosomes. 7. the kinetochore of each chromatid is attached to a kinetochore spindle fiber; polar spindle fibers stretch from each spindle. 9. centromeres of chromosomes are in alignment on a single plane at the center of the cell, on a metaphase plate 11. involved in organizing chromosomes 13. sister chromatids part and become daughter chromosomes that move towards spindle poles
