← Nature & AnimalsWhich outcome impairs nutrient absorption when stomata close?
A)Decreased xylem water flow✓
B)Increased parenchyma cell growth
C)Enhanced phloem sugar transport
D)Accelerated root cellular respiration
💡 Explanation
Closing stomata stops transpiration, which significantly reduces xylem water flow because the cohesion-tension mechanism relies on continuous water column; therefore nutrient uptake decreases, rather than being impacted by other cellular activities within parenchyma, phloem, or roots.
