Across
  1. 1. the protein channels that allow water to enter and leave a cell
  2. 3. a material that dissolves the solute
  3. 5. water loving
  4. 8. a small fluid filled sac within a cell
  5. 10. water fearing
  6. 11. a mixture in which a solute is dissolved into a solvent
  7. 12. the movement by energy of molecules across a cell membrane from low to high concentration (2 words)
  8. 13. transport the movement of molecules across the cell membrane without the need for energy
  9. 14. moving large materials out of a cell
  10. 17. made of many cells
  11. 18. taking large materials into a cell
  12. 19. the concentration inside of the cell is equal to the concentration outside of a cell
  13. 20. a semipermeable membrane made of a double layer of lipids that surrounds a cell (2 words)
Down
  1. 2. a solution with the same concentration of solutes compared to another solution
  2. 3. a material that is dissolved in a solvent
  3. 4. a solution with lower concentration of solutes compared to another solution
  4. 6. a solution with higher concentration of solutes compared to another solution
  5. 7. the diffusion of small, hydrophilic molecules across the cell membrane that requires a protein to help transport the molecule across the cell membrane (2 words)
  6. 9. the gradual change in concentration of a solute in a solution (2 words)
  7. 15. the movement of molecules from an area of higher concentration to an area of lower concentration
  8. 16. the diffusion of water molecules through a semipermeable membrane from higher concentration to lower concentration until equilibrium has been reached
