What is transpiration caused by

Transpiration is the loss of water from the plant through evaporation at the leaf surface. ... Transpiration is caused by the evaporation of water at the leaf–atmosphere interface; it creates negative pressure (tension) equivalent to –2 MPa at the leaf surface. Transpiration happens when plants release water vapor from tiny holes, called stomata, in their leaves. ... Transpiration increases because at warmer temperatures plants open up their stomata and release more water vapor. Humidity – If the air around the plant is too humid, the transpiration and evaporation rates drop. Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 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 is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. ... This transpired water must be replaced by the transport of more water from the soil to the leaves through the xylem of the roots and stem. Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. Transpiration is an important factor in the water cycle as it is one of the major sources of water into the atmosphere. Definition of Transpiration: Transpiration is the process of water movement through a plant and its evaporation from aerial parts especially from leaves. Its Type: Cuticular Transpiration. Lenticular Transpiration. Stomatal Transpiration. The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
