Effect of light exposure on the number of daughter cells. A: LD conditions. Light exposure was the same as in Fig. 8B. B: LDL conditions. PAR and the light exposure patterns were the same as in Fig. 8C. C: L1L2 conditions. PAR and the timing of L1 and L2 periods were the same as in Fig. 8 D. Light intensities are as indicated (PAR values are in m-2 s-1), all panels.
