Summary Introduction
Introduction: Casparian strips are the bands made of suberin (sometimes lignin) found on the endodermal cells, which tightly connects each cell’s plasma membrane. It is a feature found in the roots of higher plants. It creates a barrier between the endodermal cell wall that enables the water flow through the endodermal cytoplasm.
