Translocation theories refer to the process that explain water transportation in plants. We found three great theories: capillarity, root pressure and cohesion. Capillarity refers to the property that displays water when encounterd with small tubes, water "sticks and climbs" through the tube. The smaller the diameter the greater the climbing. Root pressure, refers to the effect salts and minerals absorbed in root, along water, exert in the content previously absorbed. That is, the "new generation of nutrients" pushes upward nutrients previously absorbed. Finally, cohesion theory is similar to capillarity. It refers to the property water molecules have to keep in close contact, due to their hydrogen bonds. Water forms a continuum through the plant. Water is losed through evapotranspiration in the leaves, so as water is losed, water from the stem starts to move. In that way water keeps the "continuum" and fills the gap that evaporated water left.
