Students in a biology class conducted an experiment to determine the effect of temperature on the rate of photosynthesis in a plant. They placed an Elodea plant
into a tube filled with water. A student then placed the test tube under a light and
slowly increased the temperature of the water.
They recorded their results and displayed them on a graph shown.
