  • Awater potential in roots decreases; direction of water movement out of the roots
  • Bwater potential in roots increases; direction of water movement into the roots
  • Cwater potential in soil decreases; direction of water movement out of the roots
  • Dwater potential in soil increases; direction of water movement into the roots
