Light intensity, carbon dioxide concentration and temperature are three factors that affect the rate of photosynthesis.
How would you investigate the effect of light intensity on the rate of photosynthesis?
The effect of light intensity on photosynthesis can be investigated in water plants. the light intensity is proportional to distance it will decrease as the distance away from the bulb increases so light intensity for the investigation can be varied by changing the distance from the lamp to the plant.
