Match each item to the correct phase




  • Chromosomes become visible and nucleus begins to dissolve.
  • Chromosomes are split and moved to opposite sides of the cell.
  • The cell begins to split, and two new nuclei begin to form.
  • Chromosomes attach to spindle fibers and align along the center of the cell.
  • Prophase
  • Metaphase
  • Anaphase
  • Telophase
