Prosenchyma - a plant tissue, consisting of elongated cells with interpenetrating tapering ends, occurring especially in vascular tissue. Xylem - a complex tissue in the vascular system of higher plants that consists of vessels, tracheids, or both usually together with wood fibers and parenchyma cells, functions chiefly in conduction of water and dissolved minerals but also in support and food storage, and typically constitutes the woody element Collenchyma, in plants, supports the tissue of living elongated cells with irregular cell walls. Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross-section  Sclerenchyma is the tissue that makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin.    

Complex permanent tissues features.

Complex permanent tissues are made of different cells.

Complex permanent tissues have various types of cell.

  Anatomy -  the scientific study of the structure of human or animal bodies

The middle lamella -  a layer of pectinaceous intercellular material lying between the walls of adjacent plant cells The primary wall is the cellulose-containing layer laid down by cells that are dividing and growing. To allow for cell wall expansion during growth, primary walls are thinner and less rigid than those of cells that have stopped growing The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane.    

Meristem - a region of plant tissue, found chiefly at the growing tips of roots and shoots and in the cambium, consisting of actively dividing cells forming new tissue. Sclereid -  Sclereid is a reduced form of sclerenchyma cells with highly thickened, lignified cellular walls that form small bundles of durable layers of tissue in most plants Collenchyma, in plants, supports the tissue of living elongated cells with irregular cell walls. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions.
