Definition
A companion cell (PO:0000400) that has dense cytoplasm, a small vacuole, proplastids rather than chloroplasts, and abundant and highly branched plasmodesmata linking it to adjacent mesophyll cells. Source: PMID:21669666, PO_REF:00011
Comment
Intermediary companion cells translocate high concentrations of raffinose-family oligosaccharides and are found in plants that use symplastic phloem loading. Unlike sieve tube elements (PO:0000289), intermediary companion cells retain their nuclei and other organelles at maturity.
