← Nature & AnimalsWhich hydrostatic outcome facilitates water movement in trees?
A)Negative pressure from transpiration pull✓
B)Phloem loading increases sugar concentration
C)Active protein pumping boosts root water
D)Stomata close, ceasing water exchange
💡 Explanation
Transpiration creates negative or tension pressure in xylem. The cohesion-tension mechanism pulls water upwards continuously because of cohesion, therefore water loss is balanced rather than exclusively root uptake, affecting osmosis.
