write down the nature of cells of sclerenchyma
Answers
Answer:
Mature sclerenchyma cells are usually dead cells that have heavily thickened secondary walls containing lignin. The cells are rigid and nonstretchable and are usually found in nongrowing regions of plant bodies, such as the bark or mature stems. ... They are found mainly in the cortex of stems and in leaves.

Answer:
Sclerenchyma cells have thick, lignified secondary walls, lack cell contents at maturity, and occur throughout all plant tissues. These features make sclerenchyma tissues hard, rigid, and somewhat brittle. Sclerenchyma cells can occur as aggregates within ground tissue (sclereids or stone cells or as elongated fibers. In this context, sclerenchyma provides mechanical strength to stems (fibers in hemp and flax) and reproductive structures (the texture in pear flesh, the stony shells of nuts and cherry pits).
