TREE BARK Meaning and
Definition
-
Tree bark is the protective outer layer that covers the trunk, branches, and twigs of a tree. It serves as a tough, resilient barrier against environmental stressors, such as extreme temperatures, pathogens, and physical damage. The bark is composed of several layers, each with specific functions and characteristics.
The outermost layer, known as the cork cambium or phellogen, continuously produces a layer of protective cells called cork, also referred to as periderm. This cork layer acts as a waterproof shield, preventing excessive water loss and protecting the tree from external injuries. It is composed of dead cells filled with suberin, a waxy substance that provides elasticity and resistance to decay.
Below the cork layer lies the phloem, a living tissue responsible for transporting sugars and nutrients throughout the tree. It is an inner layer of the bark that nourishes and supports the growth of various parts of the tree. The innermost layer is the cambium, which is a thin, cellular tissue responsible for producing new bark and wood cells. It not only contributes to the tree's growth in thickness, but also repairs any damages that may occur to the bark.
Tree bark exhibits a wide range of textures, colors, and patterns, allowing for the identification of different tree species. It also holds historical and cultural significance in various societies, as it has been used for traditional medicine, art, and as a raw material for crafts. Additionally, the bark of certain trees may possess unique properties, such as antimicrobial or anti-inflammatory compounds, which have been used for medicinal purposes.

Etymology of TREE BARK
The word tree bark has a straightforward etymology.
The Old English word treo (meaning tree) combined with bærc (meaning bark) to form Treobærc. Over time, the word evolved and transformed into Tree Bark in Modern English.
The term bark itself originates from the Proto-Germanic word barkuz, which referred to the exterior covering of a tree. This word likely came from the Proto-Indo-European root *bherg- or *bhereg-, meaning to break or to split, reflecting the visual appearance of the bark.
Overall, the etymology of tree bark is rooted in Old English and comes from combining words for tree and bark.
