Which of the following statements correctly describes the transport of water across plant roots?
The apoplast pathway involves the movement of water through the cytoplasm via plasmodesmata.
The Casparian strip in the endodermis blocks the apoplast pathway, forcing water to enter the symplast pathway.
Water enters root hair cells from the soil because the water potential of the soil is lower than that of the root cells.
The vacuolar pathway is the fastest route because water does not have to cross any cell membranes.
