Which outcome occurs when water availability decreases and xylem sap's osmotic pressure gradients change within a plant’s root system undergoing transpiration?

💡 Explanation

Decreasing water can lead to xylem embolism through cavitation because increased negative water pressure will compromise the transpirational cohesion-tension mechanism, therefore leading to air bubbles, not increased absorption, rather than maintained water gradients.
