← Nature & AnimalsWhich outcome occurs when leaf surface cells maintain constant turgor pressure?
A)Increased xylem water column cavitation
B)Accelerated root cortex cell apoptosis
C)Controlled stoma aperture regulation✓
D)Downregulation of phloem sucrose loading
💡 Explanation
Controlled stomatal aperture results because guard cells modulate turgor pressure affecting the stoma through the turgor pressure mechanism; therefore gas exchange will regulate rather than water loss becoming uncontrollable with an open stroma.
