Systems of Photosynthesis

The connection to hot and dry conditions comes from the fact that all the plants will close their stomata in hot and dry weather to conserve moisture, and the continuing fixation of carbon from the air drops the CO 2 dramatically from the atmospheric concentration of nominally 380 ppm (2004 value). If the CO 2 compensation point is lower on the above scale, the plant can operate in hotter and ...
