Abstract Nanoparticles (NPs) can induce toxic effect due to their small size, surface reactivity, and chemical nature. They have been used to improve the efficiency
and quality of various industrial products. The release of nanoparticles from such
nanoproducts can bring them in contact with the primary producer, plants. They can
have positive as well as negative effect on the plants. NPs have positive effect on
seed germination, plant growth, and development mainly due to increased water and
nutrient uptake, photosynthesis, and secondary metabolism by regulating genetic
material and changing cell morphology. The negative effect on plant growth and
development on NP exposure is mainly due to reduced photosynthesis, altered
genetic material expression, and oxidative or abiotic stress induced by them. One or
more factors can act simultaneously or individually to induce positive or negative
