What are the factors that affect the rate of photo synthesis?

The rate of photosynthesis is influenced by several key factors, including light intensity, carbon dioxide concentration, and temperature. Higher light intensity generally increases the rate of photosynthesis up to a certain point, while higher carbon dioxide levels can enhance the process as well. Additionally, temperature affects enzyme activity involved in photosynthesis; optimal temperatures promote higher rates, while extreme temperatures can inhibit the process. Water availability is also crucial, as it serves as a raw material for photosynthesis and affects plant health.
