Quizplus · Accepted Answer

The Casparian strip is a specialized structure in the roots of plants that acts as a barrier to water and solutes. It is made up of a band of cells with a waterproof barrier made of suberin, and it forces water to pass through cells before entering the xylem. This helps regulate the movement of water and nutrients into the plant and prevents the movement of harmful substances into the xylem.
