As much as we vertebrates need to regulate our bodies salinity by peeing, “transpiration” help plants evacuate the excess of soil water they pump from the ground to convey nutrients through their roots.<ref>Plants roots actually absorbes water thanks to osmotic laws, by the use of metabolic energy in cells to increase the salts’ concentration inside the roots, so that the soil water is less concentrated and gets in. However, this process called “active” is less important that of the “passive” absorption of water caused by the leaves’ transpiration that creates a suction from bottom to top, throughout the plants tissues. | As much as we vertebrates need to regulate our bodies salinity by peeing, “transpiration” help plants evacuate the excess of soil water they pump from the ground to convey nutrients through their roots.<ref>Plants roots actually absorbes water thanks to osmotic laws, by the use of metabolic energy in cells to increase the salts’ concentration inside the roots, so that the soil water is less concentrated and gets in.
