Across
  1. 3. Active cell membrane surround particle and incloses it in vesicle to bring into cell in bulk.
  2. 9. Substance can cross membrane without energy input.
  3. 11. Move materials from low to high concentration but require energy.
  4. 12. Concentration of molecules.
  5. 13. Difference in concentration of molecules across a distance.
Down
  1. 1. Passive help from transport proteins to carry substance through cell membrane along concentration gradient.
  2. 2. Passive water molecules diffuse from high to low concentration.
  3. 4. Pressure exerted on cell wall.
  4. 5. Solution concentration is lower than inside cell (osmosis)
  5. 6. Solution concentration is higher than inside the cell (osmosis).
  6. 7. Active bulky material exits cell.
  7. 8. Solution inside and outside the cell are equal (osmosis).
  8. 10. Passive movement of molecules from an area of high concentration to low, most simple.
