Table III. Unknown parameters.
Parameters that could not be estimated with confidence from light micrographs across species (these are referred to in the text as unknown parameters) are listed, with ranges and default values used in simulations.
| Parameter | Symbol | Range | Default | Units |

| Membrane permeability | Pm | 0–160 | 40 | μm s−1 |
| Effective Poiseuille radius of cell wall | Ra | 0–10 | 3 | nm |
| Ratio of true palisade horizontal connectivity to the value from microscopy | ρfcph | 0–1.0 | 0 | – |
| Ratio of true cell wall thicknesses to values from microscopy | ρta | 0.2–1.0 | 0.2 | – |
| Vertical temperature gradient in leaf | ΔT | 0–0.2 | 0.1 | °C |
