Question

which mechanism plants adopt to avoid overheating?​

Answer 1

I've read that efficiency of photosynthesis is only like 5%, and it operates on visible light spectrum, not infrared (which is heat radiation). Which means light should either be absorbed and increase plant temperature, or reflected, and heat what's around the plant. But when you get near or touch plants under sunlight, they are at ambient temperature. In contrast, if you touch a metal plate, ceramic tile, rubber, plastic, asphalt, concrete, sand etc, that's exposed to strong sunlight, they are very hot, either because they reflect heat onto you (sand), or because they absorb heat and their temperature is high (asphalt). But with plants, it seems like neither happens, and it stays cool.
