Across
  1. 3. A measure of the force driving osmosis.
  2. 4. diffusion of water through a semipermeable membrane.
  3. 5. Water soluble materials move across the plasma membrane in the direction of the concentration gradient.
  4. 8. Plasma membrane can move small particles in or out of the cell opposite of the normal direction they usually flow by diffusion.
  5. 11. Moves large quantities of material into or out of the cell.
  6. 12. Has the same concentration of dissolved substances as the fluid in the cell.
Down
  1. 1. A solution that is less concentrated than the intracellular fluid.
  2. 2. Particles move from higher concentration to lower concentration.
  3. 6. regulates what cab enter and leave based on the cell's needs.
  4. 7. A solution that is more concentrated than the cellular fluid.
  5. 9. constant movement of particles from a region of relatively high concentration to one of lower concentration.
  6. 10. The passage of water and dissolved materials through a membrane as a result of mechanical force on one side.
