Casparian strip on radial & transverse anticlinal walls of endodermis

Two schematic diagrams showing the arrangement of the Casparian strip in the endodermis cell walls (left in a 3-D mode), and the thick-walled endodermis at a later stage of development (right in a transverse sectional view).

Identify cortex, passage cell in the endodermis, pericycle, protoxylem and protophloem.
