← Nature & AnimalsWhich risk increases when endodermal Casparian strips malfunction?
A)Unfiltered soil toxins enter xylem✓
B)Phloem sap loss increases rapidly
C)Carbon fixation rates sharply decrease
D)Stomata close under water strain
💡 Explanation
A malfunctioning Casparian strip allows apoplastic transport to bypass control because the suberin deposits prevent filtered water uptake; therefore unfiltered toxins contaminate the plant's vascular system, rather than symplastic water selection occurring first with its required filtration process.
