Fibers 2.Schleroids Long spindle shaped cells. They usually occur in strands. Within a stand ,the fibers overlap. Walls are not highly hydrated. Supporting elements in plant parts that are no elongating. Function of Schlerenchyma Schlerenchyma cells are strong,thick cells that provide most of the support in plant. Enable plant organs to withstand various strain, bending, weight and presssure without damage to the thin softer cells.
