Tracheary elements function in the conduction of water and dissolved substances such as mineral nutrients from the roots to the shoot system. Tracheary elements can be distinguished from fiber cells (PO:0025407) by the presence of bordered pits, although there are intermediate forms called fiber tracheids (PO:0000355).</rdfs:comment> <obo_purl:IAO_0000115>A native plant cell (PO:0025606) that has a lignified cell wall with secondary thickening and bordered pits.</obo_purl:IAO_0000115> <metadata:treeView rdf:resource="http://purl.obolibrary.org/obo/PO_0005352"/> <oboinowl_gen:hasExactSynonym>管状要素 (Japanese, exact)</oboinowl_gen:hasExactSynonym> <oboinowl_gen:hasExactSynonym>elemento de traqueida (Spanish, exact)</oboinowl_gen:hasExactSynonym> <oboinowl_gen:hasOBONamespace>plant_anatomy</oboinowl_gen:hasOBONamespace> <metadata:obo/part_of rdf:resource="http://purl.obolibrary.org/obo/PO_0005352"/> <oboinowl_gen:hasDbXref>PO_GIT:440</oboinowl_gen:hasDbXref> <rdfs:label>tracheary element</rdfs:label> <oboinowl_gen:id>PO:0000290</oboinowl_gen:id> <oboinowl_gen:inSubset rdf:resource="http://purl.obolibrary.org/obo/po#CL"/> <oboinowl_gen:inSubset rdf:resource="http://purl.obolibrary.org/obo/po#TraitNet"/> </owl:Class> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/PO_0000301"> <rdfs:subClassOf> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/PO_0000290"> <metadata_def:mappingSameURI rdf:resource="http://purl.obolibrary.org/obo/PO_0000290"/> </rdf:Description> </rdfs:subClassOf> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/PO_0002003"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/PO_0000290"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/PO_0025444"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/PO_0000290"/> </rdf:Description> <rdf:Description rdf:about="http://purl.obolibrary.org/obo/PO_0025445"> <rdfs:subClassOf rdf:resource="http://purl.obolibrary.org/obo/PO_0000290"/> </rdf:Description> </rdf:RDF>
