Which greenhouse crops are mentioned as benefiting from a carbon dioxide enriched atmosphere?

Step-by-step solution

The C3 and C4 plants respond differently to CO2 concentrations. At low light conditions neither group responds to high CO2 conditions. At high light intensities, both C3 and C4 plants show increase in the rates of photosynthesis. What is important to note is that the C4 plants show saturation at about 360 µlL-1 while C3 responds to increased CO2 concentration and saturation is seen only beyond 450 µlL-1. Thus, current availability of CO2 levels is limiting to the C3 plants. The fact that C3 plants respond to higher
