Electron microscopy micrographs of a an ultrathin-section of a root treated with 1000 mg/kg NNM TiO2 (imaged with TEM) together with a magnification (A1, outside of the root) and corresponding EDX spectra of selected spots (Spectrum 1 and 2) and b an ultrathin-section of a root treated with 1000 mg/kg P25 TiO2 (imaged with STEM) together with a magnification (B1, inside of the root) and corresponding EDX spectrum of the selected particle. c Represents a particle at a location different from b, but also inside a cell. EDX spectra were collected from the center of the particles. The copper (Cu) peak that is present in all spectra originates from the grid material
