What happens to the rate of photosynthesis as light intensity increases?

As light intensity increases, the rate of photosynthesis also tends to increase steadily, up to a certain point. This is because light is one of the key factors that drive the process of photosynthesis. When there is more light available, plants have more energy to convert carbon dioxide and water into glucose and oxygen, which is their method of storing energy.

However, it's important to note that this increase in photosynthesis rate only continues until other factors, such as carbon dioxide concentration or temperature, become limiting. Once those factors are no longer able to support a higher rate of photosynthesis, the rate will plateau.

Understanding this relationship emphasizes the importance of light in photosynthesis and helps explain why plants in low-light conditions may not grow as effectively.
