A group of students did a experiment to test how temperature affect the rate of photosynthesis in an Elodea plant they increased and decrease the temperature each plant was exposed to and then measure the number of oxygen bubbles that were produced the graph below shows the results of the experiment according to the graph which of the following statements is correct? A) as temperature increases the rate of photosynthesis constantly increases.

B) as temperature increases the rate of cellular respiration constantly increases.

C) The rate of photosynthesis increases with temperature up to 30°C and then decreases.

D) The rate of cellular respiration increases with temperature up to 30°C and then decreases.
