Lignin

Real World Example

Imagine trying to build a sandcastle on a windy beach; without any support, your structure quickly collapses. This is similar to how plants rely on lignin to provide strength and stability to their cell walls. Just as wooden stakes driven into the sand can keep the castle from falling apart, lignin acts like a scaffold, hardening the cell walls of vascular tissue to maintain the plant's structure and allow it to stand tall against environmental stresses.
