What plant organs play a major role in water evaporation?

Leaves play the main role in water evaporation. By their shape and the amount of wax, you can determine in what climate a given plant lives. The evaporation of water is very important, as the remaining water that has not been used in photosynthesis must flood the cells. Also, due to the evaporation of water, thermoregulation occurs. In hot climates, water evaporates so that proteins from the heat do not begin to break down. Sometimes from excessive evaporation of water, the leaves are covered with wax. Water can evaporate, but in very small quantities.
