Can a tree survive without bark?

    It would be difficult since bark acts as a protective layer for the tree against pests such as insects and fungi.  The bark consists of two layers – the periderm and the secondary phloem.  The periderm, colloquially known as the outer bark, is composed of the cork and the cork cambium.  The cork cambium actively divides interior-wise and exterior-wise to produce two distinct layers.  The exterior layer is called cork which is filled with the waxy substance, suberin, which protects the interior, and more vulnerable, cells such as vascular tissue from pests and mold.  This cork is the same cork that is used in wine bottles that prevents water and gas penetration.  The interior layer is called phelloderm and does not contain suberin and, therefore, can still transport gasses, fluids, and nutrients.
