Which consequence results when a plant stem's water column cavitates?

💡 Explanation

Cavitation introduces air bubbles blocking water's continuous pathway; thus reduced xylem transport occurs because the cohesion-tension mechanism fails due to disrupted transpirational pull along water. Therefore, efficiency drops, rather than increasing root absorption or affecting phloem transport directly.
