<P> In plant anatomy , the Casparian strip is a band of cell wall material deposited in the radial and transverse walls of the endodermis , and is chemically different from the rest of the cell wall - the cell wall being made of lignin and without suberin - whereas the Casparian strip is made of suberin and sometimes lignin . The Casparian strip might be viewed rather like mortar in a wall that blocks the passive flow of materials such as water and solutes . Water and solutes are pumped into the stele through special endodermal cells called passage cells . The Casparian strip prevents those from leaking back out to the cortex . The band was first recognized as a wall structure by Robert Caspary ( 1818 -- 1887 ) . </P>
