Quizplus · Accepted Answer

The root endodermis contains suberin in the form of a band called the Casparian strip. This band prevents water and minerals from passing through the spaces between the endodermal cells, and instead forces them to pass through the selectively permeable membranes of the endodermal cells. This allows the endodermis to selectively control which substances pass into the vascular tissue system of the root.
