Translocation (botany)
Translocation in vascular plants means the movement of organic molecules and some mineral ions.  Movement of water from the soil to the leaves occurs in xylem vessels as the result of Transpiration. Transpiration, the evaporation of water from leaves, causes a pull on the water column due to the forces of cohesion between water molecules formed due to hydrogen bonds which causes the water to move upwards. Organic materials,  mainly produced in the leaves, are moved around the plant in the living cells of the phloem by a process called translocation.
