WebAbstract. In this review, I first address the basics of gas exchange, water-use efficiency and carbon isotope discrimination in C 3 plant canopies. I then present a case study of water-use efficiency in northern Australian tree species. In general, C 3 plants face a trade-off whereby increasing stomatal conductance for a given set of conditions ... WebThe fish uses a special gas exchange organ (gills). It has a large surface area and a short distance for gas exchange to the blood capillaries. Water flows over the filaments, and oxygen can diffuse down its concentration gradient the short distance between water and blood. Carbon dioxide diffuses the opposite way down its concentration gradient.
