The function of key structural features are listed in table:epidermaltissue. It is the outermost cell layer of the plant body and plays a protective role in the plant. The epidermis is a single layer of cells that covers plants' leaves, flowers, roots and stems. phloem vessels (made up of sieve tubes and companion cells).xylem vessels (made up of tracheids and vessels).We will examine two types of permanent tissue: The process of developing a particular structure suited to a specific function is known as cellular differentiation. Once cells develop to perform this particular function, they lose their ability to divide. The meristematic tissues give rise to cells that perform a specific function. Figure 4.5 shows a micrograph image of a root tip.įigure 4.5: Image shows meristematic tissue in a root tip as observed under an electron microscope. ![]() Meristematic tissue is found in root tips as this is where roots are growing and where dividing cells are produced. Table 4.1: Structural adaption and function of meristematic tissue The following table highlights how the structure of the meristematic tissue is suited to its function. Diagramįigure 4.3: Meristematic cells in the growing root-tip of the onion, from a longitudinal section.įigure 4.4: Micrograph of meristematic tissue Examples of lateral meristematic tissue include the vascular cambium that results in the rings you see in trees, and cork cambium or 'bark' found on the outside of trees. Lateral meristems occur in woody trees and plants. Lateral meristematic tissue make the plant grow thicker. It generally makes plants grow taller or longer. Apical meristematic tissue is found in buds and growing tips of plants. Meristematic tissue contains actively dividing cells that result in formation of other tissue types (e.g. Meristematic tissue is undifferentiated tissue.
