The correct answer is:
will stop after sometime.
Effect of Light on Photosynthesis
- Effect of light is categorized under light quality, light intensity and the duration of exposure to light.
- At low light intensities, there is a linear relationship between incident light and CO2 fixation rates.
- At higher light intensities, the rate gradually does not show further increase as other factors become limiting.
- Light saturation occurs at 10 % of the full sunlight. Thus, light is rarely a limiting factor in nature
(except for plants in shade or in dense forests).
- Incident light beyond a point causes the breakdown of chlorophyll and a decrease in photosynthesis.
