A botanist conducted an experiment to test the effect of light on plants. Fifty plants of a flowering species were grown for 60 days under different lengths of artificial daylight. Flowers could be white or pink based on the parent plant genes. The amount of water and fertilizer provided was constant. At the end of the experiment, the size of each leaf for all plants is measured. What is the dependent variable in this experiment?

Answer: Size of each leaf.

Explanation:

The independent variable is the variable that is changed or controlled during an experiment in order to see what effect it has. The variable that responds to the change in the independent variable is the dependent variable. So the dependent variable is what is being measured or tested in an experiment.

In the experiment, the botanist is studying the effect of different lengths of light to see the size of the leaf which is being measured.

So, the independent variable is the lengths of artificial daylight and the dependent variable is the size of each leaf.
