Lignification
Lignification or lignification is the name given to the lignin storage in the cell walls of plants . Heavily lignified cells die and have very thick and stiff cell walls ( sclerchymatic cells ). In addition to the strengthening function for the plant, these cells also have other special functions, such as B. as aqueducts ( trachea and tracheids ) in the xylem of the bedecktsamer . The lignification enables the plant to form very stable structures. This enables it to grow to greater heights, to protect it from enemies, but also to overwinter . In general, woody plants overwinter while maintaining their aboveground structure and sprout from the buds located there in the following season.
