5. What would happen if the soil around a tall tree were contaminated by salt?
6. The tree would continue to grow just as it had before the salt contamination.
7. The tree would become stronger because of the increase of minerals in the soil.
8. The tree would require less water to maintain a water potential gradient.
9. The tree could die because the soil water potential would be lower than that of the root.
10. The tree would create more xylem to accommodate the extra mineral load.
