What does the term 'transpiration' refer to?

Transpiration refers to the process by which moisture is carried from plants to the atmosphere. During transpiration, plants absorb water through their roots, which then travels through the plant to the leaves. Here, water molecules evaporate from tiny openings called stomata, entering the atmosphere as water vapor. This process not only plays a crucial role in the water cycle but also helps regulate plant temperature and facilitates nutrient transport.

The significance of transpiration extends to its impact on local and global climates, as it contributes to humidity levels and precipitation patterns. It also highlights the interconnectivity of ecosystems, demonstrating how water moves through plants and into the environment. Understanding this process is essential for studying hydrology and plant ecology.
