The dermal tissue system in cacti enables specialized adaptations for survival in arid environments.
The specialized fleshy stem of a cactus is most likely made possible by the dermal tissue system. The dermal tissue, consisting primarily of epidermis, plays a crucial role in protecting the stem and underlying tissue, especially in desert-adapted plants like cacti.
Furthermore, the presence of structures like trichomes and cuticle in the epidermis helps to reduce water loss and protect the plant from environmental stress, allowing cacti to thrive in arid conditions.
In addition to the dermal tissue, the ground tissue in the stem of cacti also aids in support and water storage, complementing the adaptations that make cacti successful in their unique habitats.
