Factors affecting photosynthesis

How does temperature affect photosynthesis?

• Increases the rate at which enzymes work
• Gives the plant energy to perform photosynthesis
• Stops certain enzymes that interfere with photosynthesis working

A student's hypothesis is that light intensity affects the rate of photosynthesis. Which idea would be the most suitable way to test this hypothesis using the apparatus shown?

• Change the distance and see how that affects the temperature of the water.

• Change the distance and see how that affects the number of bubbles produced by the pondweed in 2 minutes.

• Change the type of plant and see how that affects the number of bubbles produced by the pondweed in 2 minutes.
