Transpiration is the biological process by which water is released in the air as water vapor through minute pores called stomata. It occurs through the aerial parts of the plant, such as leaves, stems, and flowers. Transpiration. How does Transpiration Work in Plants.
Transpiration refers to the loss of water vapor through plant stomata, mainly in the leaves. Hot, dry, and windy conditions increase transpiration rate.
Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO 2 and O 2 during photosynthesis. But air that is not fully saturated with water vapor (100% relative humidity) will dry the surfaces of cells with which it comes in contact.
Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves. In order to understand evapotranspiration, let’s explore what transpiration is in more detail.
