Which consequence weakens tall tree xylem transport when atmospheric pressure lowers?

💡 Explanation

Increased atmospheric pressure helps maintain water column stability; because cavitation, the formation of vapor bubbles disrupts water flow. Lower pressure makes xylem fluid more prone to cavitation, weakening the column, which prevents efficient transport, rather than alternatives relating to vessel disruption.
