Across
  1. 5. a protein that allows the transport of specific substances across a cell membrane.
  2. 6. the capability of a solution to modify the volume of cells by altering their water content
  3. 8. Compounds/Fatty Acids that are easily soluble in organic
  4. 10. semi-permeable membrane
  5. 11. the minimum pressure applied to a solution to stop the flow of solvent molecules through a semipermeable membrane
  6. 18. molecules that do not mix with water
  7. 19. the gradual change in the concentration of solutes in a solution as a function of distance through a solution
  8. 20. the pressure in a fluid measured at a certain point within itself when at equilibrium
  9. 21. allows polar and charged molecules, such as carbohydrates, amino acids, nucleosides, and ions, to cross the plasma membrane
Down
  1. 1. its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others
  2. 2. the movement of water across a semipermeable membrane from an area of high water concentration to an area of lower water concentration
  3. 3. and insoluble in water
  4. 4. molecules that can interact with water
  5. 7. when water molecules move from low solute concentration to high solute or low water concentration across a membrane that is not permeable to the solute.
  6. 9. a two-layered arrangement of phosphate and lipid molecules that form a cell membrane
  7. 12. describes the structure of the cell membrane as a dynamic, flexible structure made up of different components
  8. 13. the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration
  9. 14. Moving water into a cell from high to low
  10. 15. contraction of the protoplast of a plant cell as a result of loss of water from the cell.
  11. 16. Moving water out of the cell from high to low
  12. 17. Water levels are equal inside and outside the cell
