How does the level of light affect the rate of photosynthesis? Question Date: 2014-11-03

Answer 1: In photosynthesis, the energy from the sun is used to turn carbon dioxide (CO2) and water into sugar. Oxygen is a waste product. More light can mean more photosynthesis. It doesn’t necessarily mean more though. When we think of photosynthesis as a process, we can see that there are at least three things that can limit the process: light, water, and carbon dioxide. More light won’t help if we don’t have enough water and carbon dioxide.
