The following patterns were noted in the structure of roots grown in textile wastewater. Hypodermis consists of single layered thick-walled cells. The inner cortex consists of 4~6 layers of parenchymateous cells (Fig.(Fig.5).5). The number of vascular bundles is 4~7. Raphide crystals of various sizes are observable in cortical cells. The average measured root cell sizes of experimental and control plants are listed in Table Table2.2. Statistical analysis showed significant (P
