A student conducted an experiment to prove that decreasing light intensity reduces the rate of photosynthesis in an Elodea plant. The observations were recorded as given below. Oxygen Bubbles produced by an Elodea plant Which of the following is a dependent variable in the above experiment? Rate of production of oxygen bubbles Duration of the experiment Distance of plant from the light source Quantity of water used

Solution

In the above experiment, dependent variable is

Distance of plant from the light source.

The experimental data clearly shows that As the distance from the light source changes the rate of oxhygen production also changes.
