← Nature & AnimalsWhich outcome occurs when transpiration exceeds water uptake in saplings?
A)Cavitation disrupts xylem water columns✓
B)Increased root pressure prevents embolism
C)Turgor pressure maintains stomatal opening
D)Phloem transport enhances sugar distribution
💡 Explanation
Increased transpiration exceeds vascular capability, therefore cavitation occurs as xylem tension surpasses its limit; this disrupts water transport via the cohesion-tension mechanism, rather than maintaining existing pressure or alternate plant transport.
