The study looked at how different types of spinach plants react to cadmium, a harmful metal. Sixteen types of spinach were grown in solutions with cadmium, and their growth and chemical changes were measured. The results showed that when exposed to cadmium, the roots and shoots of spinach plants became smaller and had less chlorophyll. The amount of cadmium in the plants varied depending on the type of spinach. Overall, the roots of the plants stored more cadmium than the shoots.
