Bark is the outermost layer of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. [1] It overlays the wood and consists of the inner bark and the outer bark.
The main stem, larger branches, and roots of these plants are usually covered by a layer of bark. Wood is a structural tissue that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. [3]
As stems and roots mature lenticel development continues in the new periderm (for example, periderm that forms at the bottom of cracks in the bark). [citation needed] Lenticels are found as raised circular, oval, or elongated areas on stems and roots. In woody plants, lenticels commonly appear as rough, cork-like structures on young branches.
Bark – the outer layers of woody plants: cork, phloem, and vascular cambium. Branches – Bud – an immature stem tip, typically an embryonic shoot, either producing a stem, leaves, or flowers. Bulb – an underground stem normally with a short basal surface and with thick fleshy leaves.
Entada phaseoloides is a large woody liana whose stems may reach up to 18 cm (7.1 in) diameter. They are dark brown with a course bark, and are flattened laterally and spirally twisted. The bipinnate leaves are up to 25 cm (9.8 in) long, with 1 to 2 pairs of leaflets, each of which is again divided into 1 to 2 pairs of "pinnules" (leaflets ...
Secondary growth thickens the stem and roots, typically making them woody.Obstructions such as this metal post and stubs of limbs can be engulfed. In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems ...
Tree bark is often used as a mulch and in growing media for container plants. It also can become the natural habitat of lichens. Some ornamental plants are grown mainly for their attractive stems, e.g.: White bark of paper birch; Twisted branches of corkscrew willow and Harry Lauder's walking stick (Corylus avellana 'Contorta')
It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (monocots usually lack secondary growth). It is one of the plant ...
