The effect of light intensity on the rate of photosynthesis is well concluded by the result of the experiment. As the light intensity increases, the rate of photosynthesis also increases. This will happen because there is more energy provided in the process. The experiment shows that as the distance of the light goes nearer, the more the bubbles is produced. The bubbles represents the oxygen produced in the process of photosynthesis.
Answer - Option D. The higher the light intensity, the higher the rate of photosynthesis.
