PROBLEM SOLVING. “Light acclimation processes in plants act to dissipate excess of absorbed light energy and optimize photosynthesis under variable light, temperature and humidity conditions. Plant leaves solve their problem of optimal gas exchange, transpiration and photosynthesis, in a way similar to that defined by the algorithm of the cellular automation.”
