DERMAL TISSUE Meaning and
Definition
-
Dermal tissue refers to the outermost protective layer of cells in plants, which covers the entire plant body. It is composed of several types of cells that work together to form a continuous layer called the epidermis. The dermal tissue system is crucial for the well-being and functionality of plants.
The primary function of dermal tissue is to protect the plant from external threats such as mechanical damage, pathogens, and excessive water loss. The cells in the epidermis are tightly packed, forming a barrier that acts as a physical shield for the underlying tissues.
Dermal tissue also plays a role in regulating water movement in plants through specialized structures called stomata. These minute openings are scattered across the epidermis, allowing gases like carbon dioxide to enter and exit the plant during photosynthesis, while also enabling the release of excess water vapor through transpiration.
Furthermore, the dermal tissue system in plants may have specialized outgrowths such as trichomes. Trichomes are small, hair-like structures that extend from the epidermis and serve multiple functions, including reducing water loss, reflecting excess sunlight, deterring herbivores, and providing insulation.
In summary, dermal tissue is the outermost layer of cells in plants that act as a protective barrier against various external factors. It helps in preventing damage, regulating water movement, and providing other adaptations for the survival and growth of plants in diverse environmental conditions.

Etymology of DERMAL TISSUE
The word "dermal" is derived from the Greek word "derma" meaning "skin". It is ultimately derived from the Proto-Indo-European root *der- meaning "skin, leather".
The term "tissue" comes from the Old French word "tissu" meaning "a web" or "structure". It is believed to be derived from the Latin word "texere", which means "to weave".
Thus, the etymology of the term "dermal tissue" can be traced back to the combination of the Greek word "derma" and the Old French word "tissu". It refers to the specialized tissue that makes up the outermost layer of the plant, akin to the skin in animals.
