Across
  1. 2. the process by which animals convert chemical energy from food to energy the cell can use(ATP)
  2. 4. requiring oxygen
  3. 8. the molecule that the cell uses for energy
  4. 10. the organelle which respiration occurs
  5. 13. when a cell DOES NOT have to use its own energy to transport a substance across the cell membrane
  6. 18. in this type of solution, the cell will neither shrink nor swell
  7. 19. a protein that speeds up chemical reactions
  8. 21. a very diverse group of biomolecules; made of amino acids, whose sequence is encoded in DNA
  9. 23. the organelle in which photosynthesis occurs
  10. 25. a cell whose genetic information is protected by a nucleus
  11. 26. the basic unit of life
  12. 27. a type of passive transport where molecules move from areas of HIGH concentration to low concentration
  13. 29. the process by which plants convert light energy from the sun to stored chemical energy
  14. 32. biomolecule that composes the cell wall in plants and bacteria
  15. 33. the tendency of a living cell to maintain rather stable internal conditions
  16. 34. in this type of solution, water enters the cell so that it swells and bursts
Down
  1. 1. the "little organ" within the cell that has a specialized function
  2. 3. "water-liking"; polar substances are _______
  3. 5. the part of the cell that occurs within the cell membrane (but outside the nucleus, if there is one)
  4. 6. the simple sugar in which plants store the energy that they get from the sun
  5. 7. biomolecule that composes most of the cell membrane
  6. 9. the biomolecule that encodes the cell's genetic information
  7. 11. biomolecule that is the genetic information of the cell (two words; write it without the space in the middle)
  8. 12. the organelle that is responsible for synthesizing proteins from a DNA template
  9. 14. small, polar molecules cannot diffuse directly across the membrane; a special protein helps
  10. 15. an organelle that stores the cell's genetic information (DNA)
  11. 16. these organisms are always prokaryotic
  12. 17. in this type of solution, the cell will shrink
  13. 20. a cell that does not have a nucleus
  14. 22. when a cell DOES have to use its own energy to transport a substance across the cell membrane
  15. 24. a word that describes a substance that cannot mix with water (like oil)
  16. 28. the protein that helps water cross the cell membrane
  17. 30. this word to refer to the movement of WATER molecules across the membrane
  18. 31. the ultimate source of ALL cellular energy
