Question

Explain why increasing the light intensity in which a plant is growing does not necessarily increase its rate of photosynthesis

Answer 1

Answer:

So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves. ... However, once the light intensity gets high enough, the rate won't increase anymore because there will other factors that are limiting the rate of photosynthesis

Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.

As the light intensity increases, the rate of photosynthesis increases. However, the rate will not increase beyond a certain level of light intensity. At high light intensities the rate becomes constant, even with further increases in light intensity, there are no increases in the rate.
