Vegetable tissue composed of short cells with thickened or hardened walls, as in nutshells and the gritty parts of a pear. See Sclerotic.
The hard calcareous deposit in the tissues of Anthozoa, constituting the stony corals.
n. (Gr. skleros, hard; enchyma, an infusion) tissue of uniformly thick-walled, dead cells in the stem whose principal function is mechanical. The cells are usually grouped into fibers.
Plant cell type characterized by the presence of lignified secondary cell walls and the absence of cellular contents at maturity.
Sclerenchyma is a plant tissue in which the cells have greatly thickened walls impregnated with lignin and no cell contents. The tissue has a mechanical function of supporting the plant and consists of two types of cells, fibers and scleroids. Fibers are long cells with tapered ends, which are often grouped into bundles.
(skler eng´ kyma) [Gr. skleros: hard + kymus, juice] • A plant tissue composed of cells with heavily thickened cell walls, dead at functional maturity. The principal types of sclerenchyma cells are fibers and sclereids.
Strengthening tissue composed of relatively short cells (sclereids) and/or relatively long ones (fibres) with secondarily thickened cell walls of lignin and usually lacking a living protoplast at maturity.
Plant tissue type composed of dead cells with thickened walls, usually for support or protection. Two types are fibers and sclereids.
tissue composed of cells with walls thickened with lignin; sclerenchyma tissue functions primarily in strengthening and support
a type of plant ground tissue which has very thick cell walls impregnated with lignin. Important in plant support.
Plant tissue where cells possess walls thickened and hardened with lignin thus helping to support the plant.
One of the three major cell types in plants; have thickened, rigid, secondary walls that are hardened with lignin; provide support for the plant. Sclerenchyma cells include Þbers and sclereids. Plant tissue type consisting of elongated cells with thickened secondary walls for support of the plant. PICTURE 1 | PICTURE 2
mechanical tissue with heavily thickened cell walls.
dead or alive, very ridged, thick and often ligninified cell walls. there are two types, sclerids (stone cells, like in pear) and fibres (like in celery).
Sclerenchyma is a supportive and protective tissue found in plants. Sclerenchyma is composed of hard, thick, dry cells.
