Why is lignin crucial for the structural integrity of plants, and what trade-offs does its presence introduce?
Lignin primarily stores energy in plants and has little impact on structural strength or decay resistance.
Lignin is easily degraded by microbes, which is why wood rots quickly without it.
Lignin provides rigidity and decay resistance to plant cell walls, enabling taller growth but making biomass harder to break down industrially.

Why is lignin essential for the structural integrity of plants, especially trees?
Because it stores energy that plants use to grow taller.
Because it forms a rigid, decay-resistant matrix in cell walls that supports upright growth and durability.
Because it is the primary nutrient that plants absorb from soil to build wood.
