Web25 May 2024 · Sclerenchyma cells are cells of the sclerenchyma tissues. They have thick walls due to secondary walls and lignin deposition. Unlike the parenchyma and collenchyma cells, the sclerenchyma cells are dead at maturity. They lose their protoplast. Examples of sclerenchyma cells are sclerenchyma fibers, sclereids, and bast fibers. WebSclereids are created through belated sclerosis of parenchyma cells or can arise from sclereid primordia that are individualized early in development. Sclerification typically involves thickening of the cell wall, increasing rigidity. In the phloem, when tissue ceases to function in conduction cells may begin sclerification.
