Content: Just like any other factor, too much of carbon dioxide is also detrimental  to the plant. If the concentration reaches 0.05 per cent it results in the  increase of the rate of photosynthesis. The C3 and C4 plants respond differently to CO2 concentrations. At low light conditions neither group responds to high CO2 conditions. At high  intensities, both C3 and C4 plants show increase in the rates of  photosynthesis. However there are also few differences that these plants  have. The C4 plants show saturation at about 360 , while the C3 plants  responds to increased CO2 concentration and saturation is seen only beyond  450. Thus, it can be said that the availability of CO2 levels is a limiting  factor for the C3 plants. You might have heard of greenhouse crops. When greenhouse crops like  tomatoes and bell pepper are grown in these, the availability of CO2 is very  high which results in a higher yield.
