Regulating body temperature
the answer is true not false i think
The answer is B. Strengthens the
cell wall to allow plants to stand up straight and tall
Lignin is a polymer that
constitutes the cell walls of all vascular plants. It provides the mechanical
support for plants and it supplies the strength and rigidity of plant cell walls.
Structural strength provided by lignin helps large trees to reach heights in
excess of 100 m. In the absence of lignin these trees would collapse on themselves.
