Adhesion occurs when water molecules are attracted to the walls of the vessel element, which has thick walls with lignin, a stiff substance. Cohesion occurs when water molecules are attracted to each other.

WebMay 1, 1998 · Abstract. On the basis of recent results with young primary maize roots, a model is proposed for the movement of water across roots. It is shown how the complex, 'composite anatomical structure' of roots results in a 'composite transport' of both water and solutes. Parallel apoplastic, symplastic and transcellular pathways play an important ... WebDefinition: Transpiration. Transpiration is the loss of water through evaporation from the leaves of a plant into the atmosphere. Figure 1: Transpiration is the evaporation of water from the leaves in the form of water vapor. The transport of water from the soil to the leaves occurs with the use of xylem vessels and is indicated by the blue ...
