Detailed explanation-1: -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.
Detailed explanation-2: -Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
Detailed explanation-3: -Transpiration is just a subset of the evaporation process, and it’s the water that is inside plants, and then when that evaporates and moves into the atmosphere, that process is called transpiration.
Detailed explanation-4: -Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. 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.
