Across
  1. 5. Short whip-like extensions of the plasma membrane surface which propels outside substances.
  2. 6. Cellular phase for final division of the cell, indicated by the prominent cleavage furrow of the cell membrane.
  3. 7. Condensed chromatin used in replication of the cell.
  4. 9. Cellular phase for stages outside of mitosis.
  5. 12. Gel-like substance that fills the cell's interior.
  6. 13. Packages proteins for transport inside and outside of the cell.
  7. 18. Translates mRNA from the nucleus to synthesize proteins.
  8. 19. Second stage of mitosis; chromosomes are pulled to the midline of the cell.
  9. 21. Cellular phase for replication.
Down
  1. 1. Projections of the plasma membrane which were developed to increase the cell's surface area.
  2. 2. Appear when cells must undergo mitosis.
  3. 3. The "powerhouse" of the cell; where ATP is synthesized.
  4. 4. Extensions of the plasma membrane surface that can propel the cell.
  5. 8. Organelle that includes a "smooth" region for lipid synthesis and a "rough" region for protein synthesis.
  6. 10. Site where rRNA (ribosomes) are synthesized.
  7. 11. Main site for chromatin and mRNA synthesis.
  8. 14. The "suicide sac" that contributes to cellular digestion and metabolism.
  9. 15. Can neutralize free radicals because of the catalase and oxidase enzymes it contains.
  10. 16. Fourth stage of mitosis; nuclear membrane begins to develop around the de-condensing chromosomes.
  11. 17. Third stage of mitosis; chromosomes are pulled away from the midline of the cell.
  12. 20. First stage of mitosis; condensing of the chromatin and breakdown of the nuclear membrane.
