Sieve elements function mainly in longitudinal conduction of organic solutes. Classified into sieve cells (PO:0025415) and sieve tube elements (PO:0000289) based on the presence of sieve plates and specialization of sieve areas in different parts of the cell. Develops from either a cambial initial (PO:0000295), a phloem mother cell (PO:0000400), or a cell of the procambium (PO:0025275).
