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)
