Similar to the other organs of a plant, a leaf is comprised of three basic tissue systems, including the dermal, vascular, and ground tissue systems. These three motifs are continuous throughout an entire plant, but their properties vary significantly based upon the organ type in which they are located.round tissue comprises the bulk of a plant leaf and is generally comprised of a variety of cell types, the predominant of which are parenchyma. Often less specialized than other plant cell types, parenchyma cells are surrounded by thin, flexible primary walls and execute most of the plant s metabolic activities.
A tissue is a mass of similar or dissimilar cells performing a common function. The body of a vascular plant is composed of dermal tissue, Ground tissue and Vascular tissue. Dermal Tissue (Skin). Dermal Tissue is protective in function. Basing on its origin, it is classified into two types Epidermis and Periderm.Epidermis: This is the primary surface tissue of the entire plant.Epidermal cells are compactly and continuously arranged; the continuity is lost by the presence of Stomatal pores or breaks in the tissue. Covering the aerial epidermis, cutin (fatty substance) is present as an impregnation on cell wall.pidermis: This is the primary surface tissue of the entire plant.
