Figure 6. The changes in quantum yield (F_v/F_m) of P. tricornutum.

The changes in quantum yield of P. tricornutum cells grown under the LC (390 ppmv, pH 8.18) and HC (1000 ppmv, pH 7.82) and then both acclimated to different light levels (A: 60 µmol m⁻² s⁻¹; B: 460 µmol m⁻² s⁻¹) for 25–36 generations under dark or dim light (10 µmol m⁻² s⁻¹). Values are means ± SD, n = 3.
