WebPhloem, the Medium for Plant Energy Transfer. In the stems of plants is a layer of living tissue called phloem that forms a medium for the movement of a sugar-rich fluid (sap) and which is therefore a key part of the energy transport within vascular plants. Part of the phloem is made up of sieve tubes which are constructed of specialized sieve tube cells … Weband reproduction. Sugar transport takes place in phloem cells which form a continuous microﬂuidic channel network from leaf to root. The current hypothesis for phloem transport dates to the 1920s when Ernst Münch proposed that gradients in cell turgor pressure drive the bulk ﬂow of sugars and other solutes from sources to sinks [25].
