Across
- 2. equal concentration
- 5. Controls what enters and leaves the cell
- 7. When molecules pass through the bilayer without needed energy
- 9. Low solute concentration
- 10. Molecules separate with the cell membrane to leave
- 11. molecules fuse with the cell membrane to get inside
Down
- 1. Molecules move through a protein channel
- 3. used to transport molecules that can't cross the membrane
- 4. does not require energy
- 6. High solute concentration
- 8. movement of water through a semi-permeable membrane
