What is transpiration in the water cycle?

In the context of the water cycle, transpiration is the process through which water vapor is released from plants into the atmosphere. This release of water vapor contributes to the overall movement of water in the hydrological cycle. As plants transpire, they add moisture to the air, which can eventually condense to form clouds and, subsequently, lead to precipitation. Transpiration, combined with evaporation from other surfaces, plays a key role in regulating weather patterns and climate.
