The apoplast pathway in plants is interrupted by the Casparian strip. Which of the following statements about its impact on water movement is most accurate?
It forces water and dissolved minerals to enter the symplast before reaching the stele.
It facilitates the rapid movement of water through the cortex via plasmodesmata.
It prevents the passage of water into the root hair cells.
It increases the rate of transpiration by reducing the resistance to water flow.
