Question

Quizplus · Accepted Answer

Lignin is an organic substance that makes the walls of sclerenchyma cells tough and hard. It is a complex polymer that provides strength and rigidity to the cell walls, making them resistant to mechanical stress and decay. Suberin is a waxy substance that prevents water loss, while stomata are pores on the leaf surface that regulate gas exchange. Trichomes are hair-like structures that protect against herbivory, and the cuticle is a waxy layer that prevents water loss and protects against pathogens.
