The accumulation of chromium in root cells vacuoles might be due to the sequestration of chromium as a defensive process. The transport of chromium from roots to the leaves of plants was not observed as hexavalent is converted to trivalent chromium in cells of plants and it binds with cell wall, which inhibits its transfer in different plant ...
