Sclerenchyma:

1. The cell wall of sclerenchymatous tissues is thickened due to the presence of lignin.
2. The lumen is absent due to irregularly thickened walls because of the presence of pits in their walls.
3. The sclerenchyma cells are closely packed so that there are no intercellular spaces between the cells.
4. There is the presence of a prominent middle lamella between two sclerenchymatous cells.
5. The sclereids are found in plant parts like the cortex, phloem, pith, hard seeds, etc.
6. They are responsible for the rigidity of the seed coat.
