 Are we okay with using these FNA ids? They are UUID and are very long and contain dashes (e.g., 40b5fa5d-a75b-49d8-8328-b4c28d54ea66). See antheridium (PO:0025125) on dev browser for an example of how it will look.

 RW is working on modifying a perl script from JE to insert FNA synonyms into the PO file. May needs some help from JE.

 Comment: Sieve areas in sieve cells generally have narrow pores and thin connecting strands, and they are not highly specialized, but instead are fairly uniform throughout the cell wall. Typical of gymnosperms and non-seed vascular plants. Differ from sieve tube members, which have sieve plates and more pronounced specialization of sieve areas.
