Land plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. [...] Key Result Transport improvements appeared as water demand increased and CO2 dropped to current values in the Carboniferous and Permian. Stomatal regulation and high‐conductivity conduits permitted larger plants and a transition from poikilohydric to homoiohydric water relations. The evolution of conduits from hydroids through tracheids to vessels reflects the need to balance…Expand Abstract
