WebPhloem mostly contains sugar molecules dissolved in water forming a very thick sugary sap, which is food for them. And if you're wondering what these things are over here at the sides, that is some leftover cytoplasm. The cells don't lose all of their cytoplasm. And similarly, this is the cell walls. WebPhloem. Phloem vessels transport dissolved substances, such as sucrose and amino acids from parts of the plant where they are made (sources) to the parts of the plant where they are used (sinks).Leaves are sources because they produce glucose from photosynthesis and parts of the plant where sugar is stored, such as roots and bulbs, act …

"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].
