Sap is the liquid that flows inside plants. We can have one raw sap, when it is made up of water and mineral salts and it is the one that is absorbed by the roots of the plant from the ground and that runs through the plant in the direction you ascend along the xylem to bring it to the leaves. We then have one processed sap formed by water and organic substances processed by the leaves of the plant and which retraces the plant in a vertical descending direction to redistribute it to all the tissues of the plant through the crystalline tubes (phloem).
