It consist of a vessel, usually shallow, with the bottom perforated, or made of hair, wire, or the like, woven in meshes. "In a sieve thrown and sifted." 2. A kind of coarse basket. <botany> Sieve cells, cribriform cells. See Cribriform. Origin: OE. Sive, AS. Sife; akin to D. Zeef, zift, OHG. Sib, G. Sieb. A. Cf. Sift.

| sieve bone | A horizontal lamina from which are suspended the labyrinth, on either side, and the lamina perpendicularis in the centre; it fits into the ethmoidal notch of the frontal bone and supports the olfactory lobes of the cerebrum, being pierced with numerous openings for the passage of the olfactory nerves. Synonym: lamina cribrosa ossis ethmoidalis, cribrum, sieve bone, sieve plate. (05 Mar 2000) |
| sieve graft | An obsolete term for a full-thickness skin graft taken after cutting multiple holes in it with a circular punch, thus leaving islands of skin in the donor area to heal it. (05 Mar 2000) |
| sieve plate | 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. (18 Nov 1997) |
| sieve tube | The structure within the phloem of higher plants that is responsible for transporting organic material (sucrose, raffinose, amino acids, etc.) from the photosynthetic tissues (e.g. Leaves) to other parts of the plant. Made up of a column of cells (sieve elements) connected by sieve plates. (18 Nov 1997) |
| Sievert | <unit> The special name for the SI unit of dose equivalent. One sievert equals one joule per kilogram. The previously used unit, rem, is being replace by the sievert. One sievert is equal to 100 rem. Abbreviation: Sv (18 Nov 1997) |
| molecular sieve | A gel-like material with pore sizes of such ranges as to exclude molecules above certain sizes; used in fractionating or purifying macromolecules. (05 Mar 2000) |

| sievert |
A measure of dose (technically, dose equivalent) deposited in body tissue, averaged over the body. Such a dose would be caused by an exposure imparted by ionizing x-ray or gamma radiation undergoing an energy loss of 1 joule per kilogram of body tissue (l gray). One sievert is equivalent to 100 rem.
