Across
  1. 3. solution that has a lower concentration of dissolved particles compared with another solution
  2. 7. release of substances out a cell by the fusion of a vesicle with the membrane
  3. 10. part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions
  4. 11. condition or quality of allowing some, but not all, materials to cross a barrier or membrane
  5. 12. diffusion of water molecules across a semipermeable membrane from an årea of higher water concentration to an area of lower water concentration
  6. 13. process by which ATP is made using chemicals as an energy source instead of light
  7. 14. movement of molecules across a membrane from a region of lower concentration to a region of higher concentration; requires energy input by a cell
  8. 17. difference in the concentration of a substance from one location to another
  9. 18. uptake of liquids or large molecules into a cell by inward folding of the cell membrane
  10. 19. protein that detects-a signal molecule and performs an action in response
Down
  1. 1. movement of molecules across the cell membrane without energy input from the cell
  2. 2. process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water
  3. 4. diffusion of molecules assisted by protein channels that pierce a cell membrane
  4. 5. ADP - low-energy molecule that can be converted to ATP
  5. 6. ATP - high-energy molecule that contains, within its bonds, energy that cells can use
  6. 8. movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentration
  7. 9. solution that has an equal concentration of dissolved particles compared with another solution
  8. 15. solution that has a higher concentration of dissolved particles compared with another solution
  9. 16. uptake of a solid particle into a cell by engulfing the particle; see endocytosis
  10. 17. light-absorbing pigment molecule in photosynthetic organisms
