High-resolution EM images of soybean leaf tissue. All panels show the epidermis (marked with “E”) and mesophyll (“M”). No electron-dense accumulations are visible in leaf from control (A) or high nano-CeO2 treatment (B). In the high nano-ZnO treatment (C), numerous nano-sized accumulations (arrows) are visible, and are concentrated at the outer region of the epidermis.
