Plants for proper growth and development require a certain concentration of macronutrients and micronutrients. However, high concentrations of metals , both necessary and ballast are very toxic to living organisms. Plants, as nieprzemieszczające organisms during the life cycle, generated collection mechanisms governing processing , distribution and storage of ions or other substances . In recent years in plant cells have been identified and characterized initially various systems involved in the active transport of metal ions moving across the cell membrane .
