  3. 9. Expulsion of large quantities from a cell
  4. 10. The general spreading out of molecules by collision of molecules
Down
  1. 1. Movement against the concentration gradient; requires energy
  2. 2. diffusion Movement from high to low concentration via protein channel;does not require energy
  3. 3. A form of endocytosis;white blood cells engulf bacteria
  4. 4. Two molecules moving together through a protein channel
  5. 5. Water going from hypo to hypertonic across a membrane
  6. 8. Creates a vesicle when the membrane pinches inward
