Across
  1. 1. This is one half of a chromosome.
  2. 2. This part is at the center of the nucleus and acts like a copy machine for the nucleus.
  3. 9. The border around the cell that keeps certain things out and lets others in.
  4. 11. The space inside the nucleolus where they chromosomes are found.
  5. 13. The first phase of mitosis in which the nuclear membrane disappears, the centrioles move toward the ends of the cell and the spindle fibers begin to form.
  6. 14. A type of cell division in which 4 new daughter cells are made with 23 total chromosomes.
  7. 15. The length of time is takes for cell reproduction to take place.
  8. 17. The control center of the cell.
  9. 20. The first stage of cell reproduction in which the cell gets ready to divide by growing larger and copying chromosomes.
  10. 21. The second stage of cell reproduction in which the cell divides itself produces two daughter cells with 23 pairs of chromosomes; there are 4 phase.
  11. 22. The number of pairs of chromosomes in most of the cells in our body.
  12. 23. Long strands that reach across the cell during mitosis that help pull apart the chromosomes.
  13. 24. The third stage of cell reproduction in which the Cytoplasm divides separating the cells into two completely separate cells, called DAUGHTER CELLS.
Down
  1. 1. The process in which our cells increase in number in our body, there are 3 stages.
  2. 3. The border around the nucleus.
  3. 4. The two reasons we grow and increase in height and weight.
  4. 5. The name for the new cells formed during cell reproduction.
  5. 6. A cell with only 23 total chromosomes
  6. 7. The second phase of mitosis in which the spindle fibers attach to the centromeres, and the chromosomes line up in the middle.
  7. 8. These contain all the genetic information in the cell.
  8. 9. This part holds the chromatids together in a chromosome and also attached to spindle fibers during mitosis.
  9. 10. The Third phase of mitosis when the chromosomes start to split apart to opposite ends of the cell.
  10. 12. The Fourth and final phase of mitosis in which the chromosomes and spindle fibers are harder to see and two new nuclei form around each group of chromosomes.
  11. 16. The cells in which meiosis takes place in.
  12. 18. The type of cells that mitosis takes place in.
  13. 19. A cell with 23 pairs of chromosomes, or 46 total.
  14. 24. These parts Will move to the ends of the cell and pull the cell apart during Mitosis.
