Sieve plate


noun, plural: sieve plates

The perforated transverse wall between two sieve elements in vascular plants (Angiosperms).


The perforations in sieve plates allow water and dissolved organic solutes to flow along the sieve tube. The sieve plates are lined with callose. When the sieve tube is stressed or damaged more callose is deposited, blocking the pores in the sieve plates.
