Dermal tissue in plants primarily serves the function of providing insulation and protection. This outer layer acts as the first line of defense against physical damage, pathogens, and environmental factors such as excessive water loss and UV radiation. The epidermis, which is the primary component of dermal tissue, is typically covered by a waxy layer known as the cuticle that helps prevent water loss, making it crucial for maintaining plant health in varied environments. Additionally, the dermal tissue can contain specialized structures like trichomes and guard cells, which further enhance its protective roles.

In contrast, other plant tissues serve different purposes. For instance, vascular tissue is responsible for the transportation of water and nutrients, while parenchyma is primarily involved in storage and can partake in photosynthesis.
