Phloem sieve tubes The long-distance transport of solutes occurs in the phloem sieve tubes. These are made up of individual sieve elements, which are elongated cells joined together by their perforated end walls to establish a symplasmic continuum. To enable efficient solute transport, sieve el-ements are highly specialized cells.

WebThis transfer of sugars (photosynthetic) from mesophyll cells to sieve tube elements in the leaf is called as phloem loading. On the other hand, the transfer of sugars (photosynthetic) from sieve tube elements to the receiver cells of consumption end (i.e., sink organs) is called as phloem unloading. Both are energy requiring processes. WebThe phloem also contains schlerenchymal and parenchymal cells which fill additional spaces and provide support; Sieve Element Cells. Sieve elements are long and narrow cells that are connected together to form the sieve tube. Sieve elements are connected by sieve plates at their transverse ends, which are porous to enable flow between cells
Sieve elements are specialized cells that are important for the function of phloem, which is a highly organized tissue that transports organic compounds made during photosynthesis.
