Figure 8.

Direction of chloroplast movement after mechanical stimulation. Direction of chloroplast movement in the basal region (a), in the stimulus region (b), and in the apical region (c) as shown in Figure 7A was analyzed hourly after mechanical stimulation. Chloroplasts that moved toward the apex (hatched bars) and toward the base (shaded bars) are shown as percentages. The percentage of chloroplasts that showed no movement is also shown on the right outside of the column. A control result is shown in d. Data were obtained from the same group of five protonemata as in Figure 7.
