How is transpiration related to photosynthesis in plants?

Transpiration is the process by which plants release water vapor through their leaves. This process helps to create a negative pressure in the plant, allowing water to be drawn up from the roots to the leaves. This water is essential for photosynthesis, the process by which plants convert sunlight into energy. Without transpiration, there would be no water available for photosynthesis to occur, making it a crucial link between the two processes in plants.
