🦊 In this GCSE Biology video, we explain how light intensity, carbon dioxide concentration, temperature, and chlorophyll levels all influence the rate of photosynthesis in plants. These factors are critical in determining how efficiently a plant can convert light energy into chemical energy through photosynthesis. Any one of these factors can become a limiting factor, restricting the rate of photosynthesis if not present in sufficient quantities. For instance, a graph depicting the rate of photosynthesis against light intensity at different temperatures shows that even with increasing light intensity, the rate plateaus, indicating a limitation by another factor, such as temperature, carbon dioxide concentration, or chlorophyll levels. For exam purposes, it's essential to understand how to interpret such graphs and determine which factor is limiting the rate of photosynthesis under different conditions.
