Which effect weakens xylem sap ascent when root endodermis Casparian strips malfunction?

💡 Explanation

Increased apoplastic water bypass reduces mineral intake because the Casparian strip normally forces water symplastically through endodermal cells. Loss of this control elevates bulk flow, therefore lowering osmotic capacity and reducing solute acquisition, rather than raising hormone levels or affecting stomata directly.
