The evolution of lignin affected vascular plant structure and function because it moves water and give strength to the cell wall.
Lignin is a type of complex organic polymers that is the key structural substance in the supporting tissues of most plants. Lignin are important in the formation of cell wall in plant cell. Lignin moves water and give strengthens to the cell wall of the plant cell. It is one of the major component of the secondary wall of tall plants. It is produced in the cells that is related to the transport system.
So we can conclude that The evolution of lignin affected vascular plant structure and function because it moves water and give strength to the cell wall.
