← Nature & AnimalsWhich outcome occurs in arid climates when root endodermis suberization substantially increases?
A)Reduced water and nutrient uptake✓
B)Enhanced symbiotic fungal relationship
C)Increased plant temperature regulation
D)Greater vulnerability to root pathogens
💡 Explanation
Increased suberization reduces water permeability because the Casparian strip forces water through cell membranes via osmosis. Therefore, nutrient and water uptake declines, rather than enhanced symbiosis or increased heat transfer which need high flux.
