-What is the significance of the casparian strip in controlling plant solute concentration in the xylem? (think apoplastic and symplastic)
-Explain why water uptake by a plant is zero when soils are at the permanent wilting point.
-Is permanent wilting point of a plant defined by the inherent soil characteristics or by the plant growing in that soil?
-Explain the differing values of hydraulic resistance and âwall supportâ in vessels and tracheids.
