Question

Define sclerieds and fibers​

Answer 1

Explanation:

Fibres are long, thick-walled and dead cells that provide support to the internal structure of plants. Sclereids are polygonal cells that are found in fruit pulp.

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. ... Sclereids are typically found in the epidermis, ground tissue, and vascular tissue. The term "sclereid" was introduced by Alexander Tschirch in 1885.

Fibers and sclereids, both are sclerenchyma cells found in the plants, and they are simple and non-living tissues and the main function of these cells is to provide the structural support to the plants. And both cells have thick deposits of lignin in their walls.

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). They may be branched. They may occur singly (an idioblast) or in small groups.

Answer 2

Answer:

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. An isolated sclereid cell is known as an idioblast. Sclereids are typically found in the epidermis, ground tissue, and vascular tissue.

Fiber or fibre is a natural or man-made substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.
