General vascular-plant aquaporin biology and regulated membrane water permeability. Used only for mechanisms that lack Cannabis-specific measurements; not evidence for Cannabis-specific flux rates.
Visual lesson 09
Radial water transport & aquaporins
Trace water from the rhizosphere across epidermal, cortical, and endodermal tissues toward xylem through apoplastic and cell-to-cell pathways, using general plant aquaporin evidence for regulated membrane permeability where Cannabis-specific measurements are limited.
