Bark is crucial to plants because it serves as a protective barrier against various environmental threats.
The bark, particularly the outer cork layer, shields the tree from:
- Environmental Elements: Protection from sun scorching and wind drying, preventing dehydration and damage.
- Biological Threats: Acting as a defense against fungal infections and insect attacks.
- Physical Damage: Discouraging birds and mammals from feeding on the tree.
In essence, bark is a plant's first line of defense, ensuring its survival and healthy growth.
