Detailed explanation-1: -Light intensity Without enough light, a plant cannot photosynthesise very quickly-even if there is plenty of water and carbon dioxide and a suitable temperature.
Detailed explanation-2: -Oxygen is not a limiting factor as it is never considered as an element required for photosynthesis. It is released as a byproduct during photosynthesis.
Detailed explanation-3: -If the pH level was too high or too low, the rate of photosynthesis decreased (for example, when the pH reached 3 and 9). A neutral pH is optimum for the process of photosynthesis. When the pH is 7, the rate will increase to the fastest possible point.
Detailed explanation-4: -Raising or lowering the pH from 8 will negatively influence the rate of photosynthesis because RuBisCO will begin to work more slowly. When the pH reaches 6 on the low side and 10 on the high side, RuBisCO will cease working altogether.
