Endodermis with Casparian strip Pericycle Cortex Xylem Casparian strip H,O Endoderma cyloplasm B H,0 Cortex Endodermis with Casparian strip FIGURE 15.11 (a)The suberized Casparian strip of the endodermis blocks the movement of water and dissolved minerals in the cell walls and between cells.(b)As a result,water and dissolved minerals are Xylem Phloem directed into the cytoplasm of endodermal cells where subsequent use and movement is more controlled.(c)Endodermis of Smilax root. Note the darkly stained suberin of the Casparian strip
