Root ground tissue
WebIn addition, in roots that had not yet transitioned back to one ground tissue layer there were often three ground tissue layers, which is indicative of periclinal cell divisions in the endodermis ( Fig. 2 D ). In 4-d-old wild-type roots, we never observed periclinal cell divisions in the endodermis.

WebThe vascular tissue in the root is arranged in the inner portion of the root, which is called the stele (Figure 30.18). A layer of cells known as the endodermis separates the stele from the ground tissue in the outer portion of the root. The endodermis is exclusive to roots, and serves as a checkpoint for materials entering the root’s ... 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. 1. Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and root.
