Accession: PO:0025406
Name: sieve element
Ontology: plant_anatomy
Synonyms: elemento criboso (Spanish, exact), 師(篩）要素 (Japanese, exact)
Alternate IDs: None
Definition: A native plant cell (PO:0025606) that is part of a portion of phloem tissue (PO:0005417), has sieve areas in its walls, and lacks a nucleus in its mature protoplast. Source: POC:Laurel_Cooper, ISBN:0471245208
Comment: 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).
