  1. 5. A cancerous tumor that can invade nearby tissues and spread to other parts of the body.
  2. 6. A solution that doesn't change a cell's water content.
  3. 7. 2 layers make up the plasma membrane of our cells.
  4. 12. The rough endoplasmic reticulum is a busy place covered in tiny dots (ribosomes). It's where the cell makes and fine tunes proteins, kind of like a protein factory.
  5. 13. The smallest part of an element that still has the properties of that element.
  6. 18. Moving stuff in and out of cells without using energy.
  7. 19. The cell wall is like the outer armor of a plant cell. It's strong and rigid, giving the cell shape and protection.
  8. 20. The movement of water through a cell membrane.
  9. 21. Using energy to move stuff in and out of cells, even against the flow.
  10. 22. What gets dissolved in a solution.
  11. 24. "Water fearing"; a substance that does not have an affinity for water.
  12. 25. What does the dissolving in a solution.
  13. 26. Mitochondria are the cell's power stations. They make energy (ATP) so the cell can do its work.
  14. 30. What is deliberately changed or manipulated in an investigation.

  1. 1. Eukaryotic cells are like the advanced cells. They have a proper nucleus that holds the cell's instructions (DNA) and many other specialized parts. You can find them in animals, plants, fungi, and more complex life forms.
  2. 2. Undifferentiated cells that can become differentiated into one or more types of specialized cells.
  3. 3. Large organic molecules that make up all living things.
  4. 4. Informational molecules that store and express our genetic information; we get this from our parents and NOT our food.
  5. 8. Single sugar molecule; the monomer of carbohydrates.
  6. 9. Group(s) being tested.
  7. 10. Flagella are whip-like tails on some cells. They spin or whip around to help the cell move. Imagine them as the propeller on a motorboat.
  8. 11. Aspects of an experiment that are kept constant/consistent.
  9. 14. The process of cell division, where one cell splits into two identical cells.
  10. 15. Cancer-causing agents.
  11. 16. Larger nucleic acid; never broken down for energy.
  12. 17. Standard/"normal" group used for comparison.
  13. 23. The need of an organism to stay stable by regulating internal conditions.
  14. 27. When chromosomes split and move to opposite sides of the cell during mitosis.
  15. 28. Anything that has mass and occupies space.
  16. 29. The application of scientific discoveries to meet human needs and goals through the development of products and processes.
