Simple Permanent Tissue: Epidermis: • Structure: Transparent, one cell thick and is usually covered with cuticle usually has guard cells with stomata • Found on the outermost layer of the plant body such as leaves, flowers, stem & roots • Function is to protect the plant from dessication and infection. Tracheary elements, parenchyma, Sclerenchyma (fibers) Water and mineral conduction, storage of food, and support. It is divided into-tracheids, vessels, xylem fiber, and xylem parenchyma. Tissue: It is a group of cells having common origin similar or related structure and a common function. With progressive obesity, ATMs are key mediators of meta‐inflammation, insulin resistance and impairment of adipocyte function. A tissue that consists of several kinds of cells but all of them function together as a single unit is called complex tissue. Where is it located ? Tissue definition, an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism. Xylem (Greek word 'xylos'= wood) is a complex tissue that is mainly responsible for the conduction of water and mineral salts from roots to other parts of the plant. Epithelial tissue.
