Abstract
Internal cell surface areas were measured on fully expanded leaves of soybean seedlings that had been continuously exposed to 348 or 645 ppm CO2 environments. Plants grown in the high CO2 treatment had thicker leaves but less palisade cell surface area per unit leaf area. Surface area of the mesophyll per unit leaf area was unaffected by CO2. The potential ramifications of these CO2-induced changes in leaf anatomy on photosynthesis and water-use efficiency are explored.
