Radioisotopes can be used to understand chemical and biological processes in plants, because:
they are stable and can be detected easily using a geiger counter.
they are not harmful to the plants and animals they are used in.
they are used to trace the pathway of chemical reactions.
they are a natural byproduct of many biological processes.
