Across 4. an array of microtubules that radiates toward the plasma membrane from the centrosomes 5. parent cell 7. 1 chromosome of each kind 11. the copied chromosomes align in the middle of the spindle 12. the nuclear membrane breaks apart and the spindle starts to interact with the chromosomes 16. the cell splits into two daughter cells, each the same number of chromosomes as the parent 18. used to produce human tissue 21. each double helix is a 22. 2 chromosomes of each kind 23. is the indention of the membrane between the two daughter nuclei 24. barrel-shaped organelles, not found in plant cells 25. newly formed plasma membrane that expands outward until it reaches the old plasma membrane and fuses with the membrane 26. daughter cell 27. involves the building of new cell walls between the daughter cells

Down 1. two sister chromatids separate at the centromere, each duplicated chromosome gives rise to two daughter chromosomes 2. nuclear membrane form around each of the two sets of chromosomes and the chromosomes begin to spread out, and the spindle beings to break down 3. in the nucleus chromosomes condense and become visible, in the cytoplasm the spindle forms 6. chromosomes duplicate and the copies remain attached to each other 8. the main microtubule organizing center of the cell, also divides before mitosis begins 9. chromosomes separate into two genetically identical groups and move to opposite end of the spindle 10. tangled mess of thin threads (DNA and Proteins) 13. the production of a new individual 14. two identical chromatids 15. sister chromatids are constructed and attached to each other at the 17. proteins that organize chromosomes 19. continuous process that is divided into 5 phases and permits growth and repair 20. protein complexes that develop on either side of the centromere during cell division
