The bark of a tree comprisesa)All The Tissues Outside The Cork Cambium...
The bark of a tree is composed of multiple layers of tissues that are located outside the vascular cambium. The vascular cambium is a layer of meristematic tissue that produces new xylem and phloem cells, contributing to the growth in girth of the tree. The bark includes several layers, starting from the outside and moving inwards, such as the cork, cork cambium (also known as the phellogen), phelloderm, and the secondary phloem. These layers together make up the bark of the tree. The cork is the outermost protective layer, formed by the cork cambium, while the secondary phloem is responsible for transporting sugars and other organic materials throughout the tree.

Composition of Tree Bark
The bark of a tree comprises all the tissues outside the vascular cambium. It is a protective outer covering of the tree trunk and branches. The bark serves as a barrier against mechanical damage, pathogens, and extreme weather conditions.
Layers of Tree Bark
1. Outer Bark: The outermost layer of the bark is called the cork. It is made up of dead cells and provides protection to the tree.
2. Inner Bark: The inner bark, also known as the phloem, is responsible for transporting sugars and other nutrients produced by the leaves to the rest of the tree.
3. Vascular Cambium: The vascular cambium is a layer of meristematic tissue that produces new cells for both the xylem and phloem.
4. Secondary Phloem: This layer is produced by the vascular cambium and is responsible for transporting nutrients.
5. Cork Cambium: The cork cambium, also known as the phellogen, produces new cells that form the cork layer.
Function of Tree Bark
The bark plays a crucial role in the overall health and survival of the tree. It helps regulate the exchange of gases, water, and nutrients, protects the tree from external threats, and aids in the healing of wounds and injuries. Additionally, the bark serves as a storage site for essential nutrients and provides structural support to the tree.
In conclusion, the bark of a tree consists of all the tissues outside the vascular cambium, including the cork, inner bark, vascular cambium, secondary phloem, and cork cambium. Each layer of the bark has a specific function in maintaining the health and vitality of the tree.
