Bark is the outermost layer of a tree’s trunk and branches, serving as a protective barrier against various environmental factors such as extreme temperatures, pests, and pathogens. It acts as a shield, preventing the inner layers of the tree from being damaged and aiding in the transport of nutrients and water throughout the tree.
In addition to its protective function, bark also plays a role in the growth and development of trees. The cambium layer found just beneath the bark is responsible for the growth of new cells, leading to the expansion of the trunk and branches. As the tree grows, the bark stretches to accommodate the increasing volume, ensuring its continued health and vitality.
Furthermore, the appearance and texture of bark can vary greatly among different tree species, providing a unique characteristic that aids in tree identification. Therefore, it is essential to recognize the significance of bark in the overall well-being of trees and appreciate its diverse functions in sustaining their existence.#16#
