woody plant
Quick Summary
A woody plant is a perennial plant that has a persistent woody stem, which typically grows to a significant height and develops a trunk and branches. Unlike herbaceous plants, which have soft, green stems that often die back annually, woody plants possess true woody tissues developed through secondary growth. This secondary growth, facilitated by the cambium, results in an increase in stem thickness, forming wood (xylem) and bark (phloem).123
Examples of woody plants include trees, which are generally defined as having a dominant trunk and a crown shape, and shrubs, which typically have multiple stems and are shorter than trees. Woody plants are crucial components of many ecosystems, providing habitat and forming the structural basis of forests and other plant communities.425

angiospermSecondary vascular systemIn woody plants, a vascular system of secondary vascular tissue develops from a lateral meristem called the vascular cambium (Figure 8). The vascular cambium, which produces xylem and phloem cells, originates from procambium that has not completely differentiated during the formation of primary xylem and primary…
