Which force precipitates leaf wilting when soil dries?

💡 Explanation

Reduced water in soil diminishes water’s availability for root uptake, weakening the xylem transpiration pull, because this process drives water movement to leaves by creating tension; therefore, wilting occurs, rather than continued turgor due to water maintenance mechanisms.
