| Comments | Plants with the C4 pathway of photosynthesis show greater rates of photosynthesis than those with the C3 pathway. There is also a close to constant ratio between the substomatal or intercellular CO2 concentration and the CO2 concentration in the ambient air. The ratio falls between about 0.65 and 0.8 for C3 species (BNID 101760) and between 0.4 and 0.6 for C4 species. |
