Definition
A sieve element (PO:0025406) that is part of a sieve tube (PO:0025416) and has as parts sieve areas aggregated into sieve plates (GO:0097218). Source: ISBN:0471245208
Comment
Sieve tube elements have sieve areas that are specialized into those with wide pores in sieve plates and those with narrow pores in lateral sieve areas. Sieve tube elements may have inclined end walls with compound or simple sieve plates. Typical of angiosperms. Differ from sieve cells (PO:0025415), which have less pronounced specialization of sieve areas and no sieve plates.
