Medical Definition of Sieve plate
1. Perforated end walls separating the component cells (sieve elements) that make up the phloem sieve tubes in vascular plants. The perforations permit the flow of water and dissolved organic solutes along the tube and are lined with callose. The plates are readily blocked by further deposition of callose when the sieve tube is stressed or damaged.
