Sclereid - Wikipedia
Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants. [1] The presence of numerous sclereids form the cores of apples and produce the gritty texture of guavas.
Sclereid | plant anatomy | Britannica
Sclereids vary in shape and size and may be branched. They are common in seed coats and nutshells. Apart from providing some internal support for various plant organs, sclereids deter desiccation of hard seeds, such as beans, and discourage herbivory of certain…
Cell Types, Sclereids - University of Florida
Feb 24, 2023 · Sclereids are specialized cells formed in a variety of shapes. They have lignified secondary cell walls and are non-living at maturity. Their primary function is for mechanical support and protection.
2.2 Ground tissues – Plant Anatomy and Physiology
The main tissue types of the ground tissue system are parenchyma, collenchyma and sclerenchyma. Parenchyma have thin walls of cellulose, whereas collenchyma have cell walls with thickened areas of additional cellulose. Sclerenchyma cells have lignified cell walls.
Sclereid Definition and Examples - Biology Online Dictionary
Sclereids are sclerenchyma cells that are different from fibers in a way that they vary in shape. Fibers are elongated cells. Sclereids are usually isodiametric (i.e. roughly spherical or polyhedral).
10.2.2: Specialized Cells - Biology LibreTexts
Two types of specialized sclerenchyma cells that can be produced by the ground meristem are sclereids and fibers.
Sclerenchyma | Description, Types, & Function | Britannica
Sclerenchyma, in plants, support tissue composed of any of various kinds of hard woody cells. Mature sclerenchyma cells are usually dead and have thick secondary cell walls. They are commonly found as fibers or sclereids in nongrowing regions of plant bodies, such as in seed coats, bark, or vascular bundles.
Sclerenchyma Cells: Structure, Types, Functions - Biology Learner
May 1, 2024 · Sclereids are modified sclerenchyma cells, usually isodiametric or irregular in shape. They occur either singly or in groups in the plant body. The wall is thick and lignified.

Sclereids - an overview | ScienceDirect Topics
Sclereids are a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue and are developed in leaves of most halophytes (e.g., Arthrocnemum glaucum, Arthrocnemum macrostachyum, Halocnemum strobilaceum, and Sarcocornia fruticosa) (Grigore and Toma, 2017).
