Detailed explanation-1: -Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
Detailed explanation-2: -A transpiration pull is a biological process in which the xylem tissue produces a pulling force. This force facilitates the water’s ascent into the xylem vessels. Through the leaves, water is lost during this process in the form of vapour.
Detailed explanation-3: -Most of the water a plant loses is lost due to a natural process called transpiration. Plants have little pores (holes or openings) on the underside of their leaves, called stomata. Plants will absorb water through their roots and release water as vapor into the air through these stomata.
Detailed explanation-4: -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.
