Which outcome impairs water movement when root casparian strips degrade?

A)Xylem embolism formation increases
B)Gravitational water restriction decreases
C)Apoplastic pathway resistance decreases
D)Cohesion-tension mechanism immediately ceases

💡 Explanation

Permeability increases because the casparian strip normally forces water into the symplast for controlled uptake and filtration; therefore, apoplastic pathway water intake occurs too freely, rather than maintaining higher selective uptake controlled by endodermal cells.
