Cell and tissue trait diversity among (A–D) leaves and (E–G) flowers. (A) Average cross-sectional mesophyll porosity (θIAS; mm3 mm-3) for leaves, visualized by averaging across the depth of the microCT scan. Lighter colors indicate more cell material, and darker colors indicate more airspace. (B) 3D volume rendering of the intercellular airspace of leaves. Height (thickness) varies depending on the species. Numbers indicate the porosity (θIAS) of the tissue. (C) 3D volume rendering of one leaf palisade mesophyll cell from a leaf of each species. Numbers indicate the asphericity () of the cell. (D) 3D volume rendering of one spongy mesophyll cell from a leaf of each species. Numbers indicate the asphericity () of the cell. (E) 3D volume rendering of one spongy mesophyll cell from a flower of each species. Numbers indicate the asphericity () of the cell. (F) 3D volume rendering of the intercellular airspace of flowers. Height (thickness) varies depending on the species. Numbers indicate the porosity (θIAS) of the tissue. (G) Average cross-sectional mesophyll porosity (θIAS; mm3 mm−3) for flowers, visualized by averaging across the depth of the microCT scan. Lighter colors indicate more cell material, and darker colors indicate more airspace. Note that in panels (A and G), the width and height are each 600 µm, and the tissue dimensions in panels (B and F) are 600 µm × 600 µm in the paradermal plane with variable height (thickness) depending on the sample. Cells displayed in panels (C–F) are visualized at different scales.
