Temperature significantly affects the rate of photosynthesis, as it influences enzyme activity and metabolic processes within plants. Each species has an optimal temperature range within which photosynthesis occurs most efficiently. At low temperatures, enzyme activity slows, reducing the rate of photosynthesis. Conversely, excessively high temperatures can lead to denaturation of enzymes and impair photosynthetic efficiency. Additionally, temperature changes can affect the availability of other factors, such as light and water, further influencing photosynthetic rates. Understanding this relationship is vital for predicting plant responses to climate change and managing agricultural practices.
