What role does lignin play in a plant's adaptation to life on land? what role does lignin play in a plant's adaptation to life on land? transports nutrients throughout the plant prevents drying out strengthens the cell wall to allow plants to stand up straight and tall anchors the plant in the soil to allow plants to grow tall?

The answer is B. Strengthens the cell wall to allow plants to stand up straight and tall

Lignin is a polymer that constitutes the cell walls of all vascular plants. It provides the mechanical support for plants and it supplies the strength and rigidity of plant cell walls. Structural strength provided by lignin helps large trees to reach heights in excess of 100 m. In the absence of lignin these trees would collapse on themselves.
