As light intensity increases, so does the rate of photosynthesis, up until a point. Explanation: Photosynthesis, specifically the light reactions, require light to occur. The light's photons excite the electrons in the pigments of the photosystems which activates the light reactions portion of photosynthesis. The more light there is, the more photosystems in the thylakoid membrane can be activated. However, light intensity can only increase up to a certain point before the rate of photosynthesis no longer increases. Once there is a sufficient intensity of light, the ATP and NADPH that come from the light reactions will be in abundance. For the remaining part of photosynthesis to occur (the Calvin cycle), carbon dioxide is needed.
