Photosynthesis is a core component of transpiration efficiency, as the latter is defined by the ratio of photosynthesis to transpiration [1]. Furthermore, the rate of photosynthesis directly influences the intercellular CO2 concentration, which in turn dictates transpiration efficiency [2], and limitations on photosynthetic rates are intrinsically linked to the trade-offs observed in transpiration efficiency [3].

claimTranspiration efficiency is a function of the CO2 concentration gradient (Ca - Ci), where ambient CO2 concentrations (Ca) are relatively constant, but intercellular CO2 concentration (Ci) is determined by the balance between CO2 supply through the stomata and CO2 uptake by photosynthesis.
claimTranspiration efficiency is defined as the ratio of photosynthesis to transpiration (A/E) and serves as a measure of a plant's success in balancing carbon gain with water loss.
claimHigh transpiration efficiency in plants is often associated with slow growth and low photosynthetic rates because restricting CO2 diffusion limits both photosynthesis and transpiration.
