As plants evolved to taller sizes, water conduction and mechanical support were more closely linked; in fact, this still is the case in many present-day plants that have no vessels, like the conifers. Both water conduction and rigidity depend largely upon cell-wall lignification, and it is thought that it was the evolution of the biochemical synthesis of lignin that made upright land plants.
In the beginning, water conduction and mechanical support were closely linked, in fact this still is the case in many present-day plants that have no vessels, like the conifers. Both water conduction and rigidity depend largely upon cell-wall lignification, and it is thought that it was the evolution of the biochemical synthesis of lignin that made upright land plants possible (Barghoorn 1964).
