The obtained nanoparticles were of diameter 2-20 nm and were spherical in shape. This study reported that Ag was absorbed from the agar medium by the root hair of the plant and was transferred to the shoot. This study also reported the synthesis and nucleation of AgNPs within the plant tissue. In several studies it was reported that AgNPs could also be synthesized by using Brassica Juncea, in which AgNPs were reported to be in the plant biomass . Flavones, terpenoids, polyphenols and catechins are phytochemical in plants that facilitates AgNPs synthesis . Synthesizing AgNPs in plant phytochemicals can be advantageous as the water solubility of the phytochemicals simplify the process . Plant parts such as roots, fruits, seeds and other aerial parts can be used for extraction of phytochemicals, which contain polyphenols that are strong antioxidants and have redox potential . , proposed a hypothesis which stated that when flavonoids are used as reducing agents it undergoes tautomerization that releases hydrogen, transforming flavonoids into keto-form. This leads to the reduction of silver ion (Ag + ) to metallic silver (Ag). Functional groups such as hydroxy (-OH) groups are known to reduce Ag + . The size and morphology of AgNPs can be altered by selecting the plant source .
