Answer:
Sclerenchyma is not flexible.
Explanation:
Sclerenchyma cells are dead,narrow and long cells and they are devoid of prootoplasm.The walls of cells of sclerenchyma are greatly thickened with deposition of lignin. Such cell walls are called lignified. The cells of sclerenchyma are closely packed without intercellular spaces and are rigid.They are found in monocots stems,orchid roots, veins of leaves, hard coverings of seed and nuts.
