How Do Sieve Tubes Work. The tube is made of strings of enucleated but living. They are the conduits of food (mostly sugar) transport from the leaves to the rest of the plant. sieve tubes consist of sieve elements which are elongated cells, connected to each other via sieve plates to form a continous tube system that spreads. Sugars are actively transported (requires. according to his theory, the mass flow in the phloem is driven by an osmotically generated pressure gradient. sieve tubes are transport pathways interconnecting distant organs. photosynthates such as sucrose (a type of sugar) are produced in parenchyma cells of photosynthesizing leaves. sieve element, in vascular plants, elongated living cells of the phloem, the nuclei of which have fragmented and disappeared and the transverse end walls of which are pierced by sievelike groups of pores (sieve plates). it involves an active process where sugars load into sieve tubes in the leaves (source) and unload where they are needed (sink), such as roots or.
