Across
  1. 6. Wall, a non-living structure composed of the polysaccharide cellulose. Supports and protects the cell.
  2. 8. have hydrolytic (digestive) enzymes that digest food and waste
  3. 10. Creating energy from food and oxygen
  4. 11. All the chemical processes of an organism
  5. 13. Solution, the [ ] of water and the [ ] of dissolved particles inside the cell and outside the cell is equal
  6. 14. Compounds, compounds that contain both carbon and hydrogen
  7. 15. Synthesis, putting 2 molecules together by removing H20
  8. 22. Diffusion, Transport proteins help molecules that do not diffuse through the membrane get into or out of the cell
  9. 23. an increase in cell size and/or number
  10. 24. Bodies, Sorts and packages proteins
  11. 25. Transport, A carrier protein in the membrane moves molecules from LOW[ ] to HIGH [ ] (uphill) against the concentration gradient
  12. 26. assist in cell division
  13. 28. Absorption and circulation of materials
  14. 30. site of cell respiration: breaks down food molecules (glucose) to release energy (ATP)
  15. 32. have no nucleus or organelles except for ribosomes
  16. 36. Transport, Molecules move from an area of HIGH concentration to LOW concentration (downhill) with the concentration gradient
  17. 38. Solution, the [ ] of water is higher inside the cell than outside
  18. 39. it controls the movement of materials into and out of the cell
  19. 40. The maintenance of a stable environment
  20. 41. controls cell activities
Down
  1. 1. a statement of what the scientist thinks may happen in the experiment
  2. 2. to break down by adding H20
  3. 3. the movement of particles from high [ ] to low [ ]
  4. 4. obtaining food and breaking it down into a usable form
  5. 5. groups of tissues working together
  6. 6. Fluid-like material which fills the space between the cell membrane and the nucleus
  7. 7. The diffusion of WATER from high[ ] to low [ ]
  8. 9. contains green pigment chlorophyll which carries on photosynthesis. Only found in plant cells.
  9. 12. Group, is the group being experimented on
  10. 13. Compounds, compounds that do not contain both carbon and hydrogen, but may contain either carbon or hydrogen.
  11. 16. Solution, the [ ] of water is lower inside the cell than outside the cell
  12. 17. make proteinsOrgan System, groups of organs working together to perform a specific function. Enzymes, Organic catalysts that speed up the rate of chemical reactions by lowering the activation energy (the energy needed to get a reaction started).
  13. 18. breaking down food
  14. 19. The control and coordination of activities
  15. 20. The production of new organisms.
  16. 21. have a nucleus and organelles
  17. 27. when the shape of the active site changes and the substrate no longer fits.
  18. 29. taking in food
  19. 31. The removal of cellular metabolic waste
  20. 33. Building large complex models from smaller simpler ones
  21. 34. Gather background information.
  22. 35. a scientific procedure undertaken to test a hypothesis.
  23. 37. serve as storage for water, waste, or food
