Plants is the only organism that undergo photosynthesis, photosynthesis is important because it produces oxygen that we breathe and Lessens carbon dioxide that we exhale.
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis. Carbon dioxide concentration. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air.
