                      develop with a wide range of different final sizes due to
                      leaf position and nutrient availability. The aim of this
                      study was to investigate, on different organizational levels
                      of leaf growth, which parameters are affected by external
                      nutrient availability and which parameters are not affected
                      and might thus be intrinsic, general patterns of growth that
                      govern plant architecture. We found that leaf size and final
                      cell size was larger with higher external nutrient
                      availability, and that hexose concentrations in N. tabacum
                      were lower with higher nutrient availability. Despite these
                      differences, several dynamic parameters of leaf development
                      were not affected by the nutrient treatment. Leaves of all
                      sizes within a species exhibited the same relationship
                      between relative leaf growth rate and relative leaf area
                      (RLA), which is defined as the ratio of momentary and final
                      leaf area. External nutrient availability did not affect
                      chlorophyll concentration per parenchyma cell, which
                      increased linearly with leaf development. Leaves of
                      identical RLA exhibited identical cell density patterns
                      within their interveinal tissue layers. This indicates a
                      close connection between the kinematics of cell expansion
                      and RLA and, hence, reveals that kinematics are an intrinsic
                      property of growing leaves that can be scaled from the cell
                      to the leaf level.},
