Which outcome reduces water reaching leaves when soil moisture decreases?

💡 Explanation

Xylem cavitation interrupts the cohesion-tension mechanism, because air bubbles form as water tension exceeds xylem vessel strength; therefore diminished water transport occurs, rather than maintaining normal water flow via osmosis under tension.
