A section of rosemary stem, an example of a woody plant, showing a typical wood structure. A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. [1] In cold climates, woody plants further survive winter or dry season above ground, as opposed to herbaceous plants that die back to the ground until spring. [2]
The plant can grow up to 20 feet long by climbing objects and vegetation. If there is nothing for it to climb upon it will grow along the ground. It has woody stems that are pale green in color and are glabrous, the youngest of which are often square-shaped. As the vine dies, the stem turns from green to a dark brown color.
The development of lignin during vascular plant evolution provided mechanical strength, rigidity, and hydrophobicity to secondary cell walls creating a woody stem, allowing plants to grow tall and transport water and nutrients over longer distances within the plant body. Since most woody plants are perennials with a longer life cycle because it ...
A shrub or bush is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than 6–10 m (20–33 ft) tall.
A liana is a long-stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. [1] The word liana does not refer to a taxonomic grouping, but rather a habit of plant growth – much like tree or shrub.
Prostration may occur because the supporting tissues in stems are not strong enough to support the weight of the plant, causing the plant to bend until it reaches the ground. Alternatively, it may occur because of a genetic disposition for branches to grow horizontally on or just under the ground; for example, as a strategy to avoid overly ...
Older phellem cells are dead, as is the case with woody stems. The skin on the potato tuber (which is an underground stem) constitutes the cork of the periderm. [30] [31] In woody plants, the epidermis of newly grown stems is replaced by the periderm later in the year.
A chamaephyte, subshrub or dwarf-shrub is a plant that bears hibernating buds on persistent shoots near the ground – usually woody plants with perennating buds borne close to the ground, usually less than 25 centimetres (9.8 in) above the soil surface. The significance of the closeness to the ground is that the buds remain within the soil ...
