Across 2. Grabs molecule, change shape, slip to other side 5. Concetration inside and outside cell is the same 7. Molecules with both hydrophilic and hydrophobic regions 9. Movement of molecules through membrane with help of ATP or Protein 12. Animal cells Swell & Burst 14. Moves protons (H) across membrane 18. 3 Na+ out and 2 K+ in 19. Concentration outside cell is less than inside the cell 20. Movement of molecules from higher to lower concentration 21. Cell survival depends on balancing water uptake & loss 22. Movement of water across cell membrane

Down 1. Move from HIGH to LOW concentration with aid of transport proteins 3. Requires ATP and uses vesicles to release substances outside 4. Animal cells Shrink and Shrivel 6. Movement of molecules through membrane with out help of ATP or Protein 8. Transport water into and out the cell 10. Membrane is a "mosaic" of proteins and phospholipids that are constantly moving and changing 11. "Cell Eating" 13. Plant cells Stiffens 14. Plant cells Shrink 15. Movement of water across the cell membrane 16. Concentration outside cell is greater than inside the cell 17. "Cell Drinking"
