Across
  1. 4. the region of cell wall that begins to grow and extend outward to split the cytoplasm and cell membrane of a plant cell during cytokinesis
  2. 6. the name for the protective envelope that surrounds the nucleus
  3. 8. step of interphase where the DNA is replicated
  4. 9. the name of the cell cycle that produces two identical cells; also known as asexual reproduction
  5. 11. the “waist” region of the chromosome where microtubules and the replicated chromatid attach
  6. 13. step of interphase where the cell duplicates its organelles (including centrioles in animal cells) in preparation for mitosis or meiosis
  7. 14. step of mitosis where the chromosomes begin to form and the nuclear membrane breaks down
  8. 15. step of interphase where the cell grows in size and prepares for DNA replication
  9. 17. step of mitosis where chromosomes are guided by spindle fibers to line up along the metaphase plate in the middle of the cell
  10. 18. the condensed form of DNA normally found in the cell while undergoing mitosis or meiosis
  11. 19. the technical term for DNA mixed with proteins; forms chromosomes
Down
  1. 1. an optional step at the end of the cell cycle, where the cytoplasm is cut in half and the cell splits to form two cells
  2. 2. a length of microtubules or fibers which extend from the centrioles to the centromeres/chromosomes
  3. 3. alternative name for the process of asexual reproduction in single-celled organisms like bacteria or amoeba
  4. 5. a unique association of small microtubules that serve as an organizing/coordinating center for the spindle fibers
  5. 7. the name of the entire process a cell goes through to undergo cell replication/division
  6. 10. first step of the cell cycle that prepares the cell for division
  7. 12. step of mitosis where chromosomes split at the centromere and are pulled to opposite ends of the cell
  8. 16. step of mitosis where the nuclear membrane reforms and chromosomes uncondense
