Roughness parameters of four types of algal cells.
| Type 1 (µm) | Type 2 (µm) | Type 3 (µm) | Type 4 (µm) |
|---|---|---|---|
| Ra = 0.76 ± 0.076 | Ra = 3.23 ± 0.076 | Ra = 1.08 ± 0.076 | Ra = 5.01 ± 0.076 |
| Rq = 1.65 ± 0.076 | Rq = 4.44 ± 0.076 | Rq = 2.06 ± 0.076 | Rq = 6.38 ± 0.076 |
| Rt = 14.64 ± 0.076 | Rt = 27.00 ± 0.076 | Rt = 18.52 ± 0.076 | Rt = 31.60 ± 0.076 |
Ra the arithmetic mean of the elevation profile, Rq the mean square elevation profile, Rt the maximum height of profile.
