Casparian strips are found in the cells of
Casparian strips made of Suberin are present in the innermost layer of cortex i.e. endodermis. Innermost region of stele is medulla. Outermost region of stele is pericycle. Outermost region of cortex is hypodermis. Hypodermis, pericycle and medullary cells do not have casparian thickenings.
