What causes movement in the chloroplasts in the cell?

Answer 1

Light-Induced Chloroplast Movements: Chloroplast movements are light-directed responses that occur in a number of diverse plant groups including algae, moss, ferns, and angiosperms. In species that contain multiple chloroplasts per cell, exposure to dim-light causes chloroplasts to accumulate along cell walls oriented perpendicular to the incident light. When the fluence rate of light is high, chloroplasts migrate to the anticlinal walls, parallel to the incident light. These movements are thought to provide important adjustments for maintianing maximal photosynthetic performance in a variable light environment. The actin cytoskeleton causes and regulates the movements as well the adaptive function of chloroplast movmenets to the physiology of plants. The exact mechanism that causes the movement are not fully understood.

I think it's Sunlight direction
