ZnO and TiO 2 NPs measuring 25 ± 3.5 nm entered leaves of tomato plants (Raliya et al. 2015). Once inside the plant, NPs are redistributed in the stem and reach root cells via the phloem (Larue et al. 2014; Deepa et al. 2014). TiO 2 NPs (100 mg/L) applied to leaves of watermelon were translocated to leaves, stem and roots (Wang et al. 2015).
