In an experiment, the independent variable is the factor that is manipulated or changed by the experimenter to observe its effects on the dependent variable. In this case, the independent variable would likely be the amount of light each plant receives, as this is something the gardener can control and change to see how it affects the growth or yield of the tomato plants.
