Experiment demonstrating plant transpiration. A plastic bag has been secured over the branches of a pot plant. The inside of the bag has condensation on it from water transpired from the plant's leaves. Transpiration is the evaporation of water from pores called stomata in leaves. The pores open to allow carbon dioxide to enter the plant for use in photosynthesis, but this also leads to the loss of water.
