Give a conclusion about the effect of light intensity on photosynthesis. - Edexcel - GCSE Biology Combined Science - Question 2 - 2016 - Paper 1

Light intensity is a critical factor influencing the rate of photosynthesis. As light intensity increases, the rate of photosynthesis typically rises until a saturation point is reached, beyond which the rate cannot increase further despite additional light. This is because other factors such as carbon dioxide concentration and temperature may become limiting.
