You’ll Never Guess What Happened When Corn Sweated in the Sun: The Surprising Science of Plant Transpiration Ever wondered what happens when corn gets hot and sweats in the sun? Contrary to popular belief, corn doesn’t just sit there soaking up rays—it actually sweats, just like humans and other plants. This natural process, called transpiration, is far more fascinating than you might imagine and plays a crucial role in plant growth and ecosystem health. ### The Secret Life of Corn: Corn Does Sweat Too While we rarely think of plants sweating, corn is one of nature’s expert perspirers. Through tiny pores on its leaves called stomata, corn releases water vapor into the air as part of its internal cooling system. When exposed to intense sunlight and warm temperatures, the rate of evaporation increases significantly, allowing the plant to regulate its temperature and maintain optimal functioning.
