Suberin is deposited in layers outside the plasma membrane, but within the primary wall (Fig. 2-24A ). The layers also contain wax. rick moranis children nowSuberin is highly hydrophobic and a somewhat 'rubbery' material. In roots, suberin is deposited in the radial and transverse/tangential cell walls of the endodermal cells. This structure, known as the Casparian strip or Casparian band, functions to prevent water and nutrients taken up by the root from entering the stele through the apoplast. Instead, water must bypass the endodermis via the symplast. This allows the plant to select the solutes that pass further into the plant.
