lignification
Definition
- Noun:
- Process of becoming woody: "Lignification" refers to the biological process by which plant cell walls become hardened and reinforced through the deposition of lignin, a complex organic polymer. This process is essential for the structural integrity and rigidity of plants, particularly in stems and woody tissues.
Usage Examples
- (The process of becoming woody made the young tree's stem stiff and strong.)
- (Too much woodiness in plant tissues makes them harder for animals to eat and process.)
Advanced Usage
"Secondary lignification": The continued deposition of lignin in plant cell walls after initial growth, often occurring in older or more mature tissues.
- Secondary lignification in tree trunks contributes to the formation of heartwood. (The ongoing addition of lignin makes the central part of the tree denser and darker.)
"Lignification gradient": The variation in lignin content across different parts of a plant or along a single stem.
- A lignification gradient is observed from the base to the tip of the grass blade. (The amount of lignin changes from the bottom to the top of the leaf.)
Variants and Related Words

Lignified (adjective): having undergone lignification; made woody.
- The lignified roots of the old tree were extremely tough. (The roots had become hard and wood-like.)
Synonyms
- Woodiness: the quality or state of being woody.
- Sclerification: a similar process of hardening in plant tissues, often involving lignin or other substances.
