Vedclass · Answer

(C) Lignification is the process of deposition of lignin,a complex polymer,in the cell wall of plant cells. Lignin provides structural support and rigidity to the cell wall. As the cell wall becomes heavily lignified,it becomes impermeable to water and nutrients. Due to this lack of transport,the protoplast eventually degenerates,and the cell becomes dead. This is characteristic of cells like tracheids,vessels,and sclerenchyma fibers.
