Here's why:
* Outermost layer: Dermal tissue forms the outermost layer of the plant, acting as a barrier against the environment.
* Protection from damage: It protects against physical damage, pathogens, and excessive water loss.
* Different types: Dermal tissue includes:
* Epidermis: The primary dermal tissue in non-woody plants, which often has a waxy cuticle for water retention.
* Periderm: The protective tissue in woody plants, which replaces the epidermis as the plant grows.
While other plant tissues have specific functions, dermal tissue is the primary line of defense for the plant.
