A vivid exhibition of chloroplasts making use of cytoplasmic streaming (cyclosis) to move to optimum position within the cell, for maximum light absorption used in photosynthesis process. The rate of motion is usually affected by light exposure, temperature, and pH levels.
These organelles are observable as flat discs usually 2 to 10 micrometer in diameter and 1 micrometer thick. A typical cell contains about 10 to 100 chloroplasts. The video is in real time.
