While independent variable is the treatment that is varied in an experiment. It usually not dependent on any variable and can stand on it own.

The growth media that is lacking in chemical is the independent variable because it stands on it own and it can be carried depending on the experimental design it could be a chemical based growth media or no chemical like the one used in this experiment.
