Wikipedia Overview
The Casparian strip is a band-like thickening in the center of the root endodermis of vascular plants. The composition of the region is lignin and some structural proteins, which are capable of reducing the diffusive apoplastic flow of water and solutes into the stele, its width varies between species. In the root, the Casparian strip is embedded within the cell wall of endodermal cells in the non-growing region of the root behind the root tip. Here, the Casparian strip serves as a boundary layer separating the apoplast of the cortex from the apoplast of the vascular tissue thereby blocking diffusion of material between the two. This separation forces water and solutes to pass through the plasma membrane via a symplastic route in order to cross the endodermis layer.
