Biochemistry
Lignin
A complex polymer that provides structural support in plant cell walls, particularly in wood. Lignin makes plants rigid and resistant to decay.
Biological Context
Lignin is what makes wood woody. It's highly resistant to decomposition—only certain fungi (white rot) can break it down. Lignified tissues allow plants to grow tall and transport water against gravity. Coal formation involves ancient lignin that didn't fully decompose.
Business Application
Organizational lignin: the deeply embedded structures and practices that are highly resistant to change. Like biological lignin, it provides strength but can persist long after it's useful, requiring special effort to break down.
