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.
1 Tissues â Groups of cells that are similar in appearance and function, for example: 2  Epidermis is the single exterior layer that protects the stems, leaves, flowers, and roots. 3  The outside surface of the epidermis tissue is usually covered with a waxy substance called cutin, which reduces water loss.n reviewing plant physiology, plant cells are grouped into tissues based on similar characteristics, then into five distinct structures (organs). 1  Cells â individual building blocks for life processes and growth.
