Which outcome results when xylem within leaves experiences sustained negative pressure?

💡 Explanation

Stomatal closure occurs because negative xylem pressure triggers the accumulation of abscisic acid, which induces guard cell turgor, therefore restricting water loss rather than causing enhanced photosynthesis or abscission, which arise from different conditions.
