Question

Quizplus · Accepted Answer

Lignin is a complex organic polymer that provides strength and rigidity to the cell wall of plant cells. This is important for plants to be able to support their own weight and withstand the stresses of living on land, such as exposure to wind and gravity. While lignin may also play a role in preventing drying out and anchoring the plant, its primary function in adapting to life on land is as a structural component. It does not play a role in nutrient transport.
