The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
Sclerenchyma have long columns of cells, each cell is thick. The end walls of sclerenchyma are often perforated (contain holes). Xylem and phloem are often surrounded by layers of sclerenchyma

The walls of sclerenchyma cells are made tough and hard primarily due to the presence of lignin, an organic polymer. Lignin provides structural support and rigidity, allowing these cells to withstand mechanical stress. In addition to lignin, sclerenchyma walls may also contain cellulose, which contributes to their overall strength. Together, these substances enable sclerenchyma cells to play a crucial role in supporting plant structures.

Sclerenchyma
A stem requires more strength and structure, which sclerenchyma and collenchyma provide, than leaves.
collenchyma helps in making food and sclerenchyma gives mechanical support to plant body Edited answer: Collenchyma cells are thick at the corners whereas sclerenchyma cells are lignified all around. Both serve as mechanical tissue.

Sclerenchyma cells are located in the supportive tissues of plants, such as stems, roots, and seed coats. They have thick, lignified cell walls that provide rigidity and structural support to the plant.
