Question

Rama was shown two slides of plant tissues. She was told one contained parenchyma cells, while the other slide had sclerenchyma cells. How can she identify the slide with sclerenchyma cells?

Answer 1

Rama observed that sclerenchyma is dead simple permanent tissue. The walls of sclerenchyma cells are thick due to the deposition of a complex sugar called lignin while Parenchyma tissue is a living tissue with isodiametric and thin-walled cells.
