How did the evolution of lignin affect vascular plant structure and function? Select all that apply. It drives out water and strengthens the cell wall. It is one of the major constituents of the secondary wall of tall plants. It provides flexible support without restraining growth. It makes up primary walls that are relatively thin and flexible. It is synthesized in the cells that stay live and flexible at maturity. It is synthesized in the cells that become part of the transport system.

Lignin is a complex organic polymer found in the cell walls of many plants, making them rigid and woody. It provides structural support, particularly in vascular plants, which include all the land plants except mosses and their relatives. Show more…
