the height of the plant
the type of plant used
the amount of water given to the plant
the amount of sunlight the plant receives

Explanation:

In an experiment, the independent variable is the factor that the experimenter changes or manipulates. Here, the student is testing the effect of sunlight on plant growth, so the amount of sunlight is what is being changed. The height of the plant is the dependent variable (changes based on sunlight), the type of plant and amount of water should be controlled variables (kept the same to isolate the effect of sunlight).

Answer:

The amount of sunlight the plant receives
