|
amount of oxygen
|
|
|
amount of carbon dioxide

how close a light source is
|
Explanation:
Detailed explanation-1: -The wavelength of green light is thought to be the least efficient for photosynthesis.
Detailed explanation-2: -Hence, a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting.
Detailed explanation-3: -Final answer: Factors which affect the rate of photosynthesis are carbon dioxide, water, sunlight and chlorophyll.
Detailed explanation-4: -The absence of oxygen will have no effect on the process of photosynthesis. This is because the photosynthetic process utilises water and carbon dioxide to produce oxygen and carbohydrate in the presence of chlorophyll and sunlight.
