21.4. Explain briefly how an increase in light intensity can affect the rate of photosynthesis​

As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. ... At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant
