Volume (μm3) | Surface area (μm2) | Aperture (μm) | Pore area (μm2) | |
---|---|---|---|---|
Closed | 3691.06 ± 478.40 | 1651.59 ± 126.48 | 5.97 ± 0.64 | 123.88 ± 20.35 |
Open | 4603.76 ± 615.76 | 1899.29 ± 154.25 | 12.54 ± 0.56 | 262.14 ± 12.13 |
Δ (open-closed) | 912.70 ± 238.17 | 247.70 ± 47.08 | 6.58 ± 0.65 | 138.27 ± 23.71 |
Factor (open/closed) | 1.25 ± 0.06 | 1.15 ± 0.03 | 2.12 ± 0.22 | 2.17 ± 0.41 |
The values were obtained from quantifications on 3D reconstructions (volume and surface area, Fig. 2, e and g) and equatorial sections (aperture and pore area, Fig. 2, a and b) of 10 intact guard cells in their closed and open states.
