The complex tissue consist of more than one type of cells.All the cells coordinate to perform a common function.they transport water,minerals salts,food material to various parts of plant body. Table 4.1 lists the plant tissues described in this chapter and their cell types. What is the vascular system? Xylem and phloem together constitute the conducting tissues in plants. Xylem Tissues. What are complex tissues? Tissue Cell Types Function Locations Vascular tissue Xylem is made up of vessels and tracheids Phloem is made up of sieve cells and companion cells […] In tissue: Plants. 8: Tracheids. tissues. Tissues, simple or complex, act together as a unit to accomplish a collective function and are derived from meristems. Xylem can be defined as a complex tissue that is composed of four basic types of cell (tracheids, trachea, and xylem fibre and xylem parenchyma), remains in close association with phloem and has specialized functions like conduction of water and solutes, and mechanical strength. Importance of Complex tissues: In respect of physiological and economic aspects, complex tissues are of great importance. They help deter excess water loss and invasion by insects and microorganisms. A, tracheid with annual thickening; B-D, tracheids with bordered pits. (After Bhuya & Timm}. State the 3 types of tissues in vascular plants. The main function of the ground tissue is to provide support, strength, and flexibility to plants. They perform many basic plant cell functions, including storage, photosynthesis, and secretion. Composed of two or more kinds of cells. What are the functions? Ground tissue: This tissue type makes up most of a plant’s body and contains three types of cells: Parenchyma cells are the most common ground tissue cells. Each type of tissue consists of different types of cells, has different functions, and is located in different places. In case of necessity they store food materials. Vascular tissues are also called conducting tissues as they play an important role in the transportation of water and food in plants. The ground tissue of plants includes all tissues that are neither dermal nor vascular.It can be divided into three types based on the nature of the cell walls. Function of Phloem tissue: There main function is to conduct food materials, prepared in the leaves, to different parts of the plant. Plant tissues come in several forms: vascular, epidermal, ground, and meristematic. Ground, vascular and dermal. The three types of ground tissues are; Parenchyma, Collenchyma, and Sclerenchyma. What are the functions of ground tissue? Photosynthesis, storage and support. Xylem or wood is a typical complex tissue and constitutes the major portion of the vascular bundle. The vascular tissues are of two kinds: water-transporting xylem and food-transporting phloem. Primary xylem and… Read More Complex tissues are of following two types.They are Xylem and Phloem Xylem : Its main function is conduction of water and mineral salts from root to the top of plant.Primary xylem elements originate from procambuim of apical meristem.Secondary xylem elements originate from the vascular cambium of lateral meristem. Complex permanent tissue is defined as a collection of structurally dissimilar cells performing a common function or set of functions. Dermal tissue: Consisting primarily of epidermal cells, dermal tissue covers the entire surface of a plant. Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). Tissues made from aggregates of different cell types are called complex tissues. Present in vascular plants.
