Plants blink: proceeding with caution in sunlight

Like eye’s adjustment to sudden changes in light, plants have sensitive mechanisms to protect their leaves from rapid changes in radiation.
 
Plants have control mechanisms that resemble those in human senses. According to a new Weizmann Institute of Science study, plants adjust photosynthesis to rapid light changes using a sophisticated sensing system, much in the way that the human eye responds to variations in light intensity. This sensory-like regulation operates at low light intensities, when the photosynthesis machinery is most efficient but also most vulnerable to sudden light increases.
