14.

A group of students wanted to test the effect of light vs dark on photosynthesis. They had two cups of spinach leaves submerged in water, with all spinach leaves absent of oxygen. They placed one cup under a lamp, and the other cup in a dark place. They checked the amount of spinach leaves floating in each cup every minute for 15 minutes. They found that the lamp cup had all spinach leaves floating by about 7 minutes, and the dark cup had none by the end of the 15 minutes. They concluded that the spinach leaves under the lamp had undergone photosynthesis and produced oxygen which helped them to float. What is the dependent variable of this experiment?

a)

The presence or absence of light

b)

The amount of spinach leaves

c)

The amount of floating leaves
