Light-induced chloroplast movement (chloroplast photorelocation) has fascinated plant biologists since its discovery in the mid-nineteenth century. Physiological and photobiological analyses reveal that chloroplasts can move in any direction within a short time during the accumulation and the avoidance responses. The side and upper surface views of a leaf cell are shown below along with the direction of light as indi

  3. CIn Figure 2, the chloroplasts relocate to escape photo-oxidation.
  4. DIn both the figures, movement of the chloroplasts is random and does not change with direction of light.
