What type of water loss primarily occurs through leaves of plants?

The process responsible for water loss primarily through the leaves of plants is called transpiration. During transpiration, water absorbed by the roots moves through the plant and evaporates from tiny openings on the leaves known as stomata. This process is vital for regulating the plant's temperature, facilitating nutrient uptake, and maintaining physiological balance.

Transpiration plays a crucial role in the water cycle by contributing to atmospheric moisture. As water vapor is released into the atmosphere, it can lead to cloud formation and ultimately precipitation, supporting ecosystems and maintaining local hydrology.

In contrast, evaporation generally refers to the transformation of liquid water into vapor from any surface, including bodies of water and soil but not specifically from plant leaves. Infiltration relates to how water enters the soil and becomes groundwater, while runoff describes the flow of water over land that occurs when excess water cannot be absorbed. Transpiration is distinct in that it specifically pertains to the loss of water from plants.
