Now as sunlight impacts plant growth this means sunlight is an independent variable whereas the plants are dependent variable as the amounts of sunlight impact the plants. Also Rachel changes/varies or controls the amounts of sunlight to different sets of plants. Hence from the above definition of an independent variable it is clear that sunlight is an independent variable.
