Transpire
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaf, leaves, Plant stem, stems and flowers. It is a passive process that requires no energy expense by the plant. Transpiration also cools plants, changes osmotic pressure of cells, and enables Mass flow (life sciences), mass flow of Plant nutrition, mineral nutrients. When water uptake by the roots is less than the water lost to the Atmosphere of Earth, atmosphere by evaporation, plants close small pores called stomata to decrease water loss, which slows down nutrient uptake and decreases CO2 absorption from the atmosphere limiting metabolic processes, photosynthesis, and growth. Water and nutrient uptake 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. Water with any dissolved mineral nutrients is absorbed into the roots by osmosis ...
