The bark of Pinus thunbergii is made up of countless shiny layers. 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 ...
The trunk consists of five main parts: The outer bark, inner bark , cambium, sapwood (live xylem), and heartwood (dead xylem). [2] From the outside of the tree working in: The first layer is the outer bark; this is the protective outermost layer of the trunk. Under this is the inner bark which is called the phloem. The phloem is how the tree ...
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 ...
The dark horizontal lines on silver birch bark are the lenticels. [1]A lenticel is a porous tissue consisting of cells with large intercellular spaces in the periderm of the secondarily thickened organs and the bark of woody stems and roots of gymnosperms and dicotyledonous flowering plants. [2]
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.
bark The protective external layer of tissue on the stem s and root s of woody trees and shrubs; includes all of the living and non-living tissue external to the cambium. basal Situated or attached at or close to the base (of a plant or a phylogenetic tree diagram). basifixed Something attached by its base, e.g. an anther attached to the filament.

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')
