← Nature & AnimalsWhich risk sharply increases when significant xylem embolism exists in a eucalyptus tree?
A)Reduced leaf turgor pressure maintenance✓
B)Increased photosynthetic efficiency overstimulation
C)Accelerated cambial differentiation
D)Enhanced nutrient distribution via phloem
💡 Explanation
Reduced leaf turgor occurs because embolism impacts the cohesion-tension mechanism in xylem; air bubbles disrupt water transport, leading to reduced water availability in leaves. Therefore, leaf turgor declines, rather than cambial or pholem responses because embolism directly blocks water movement.
