WebRoot Development . In plants, both roots and shoots grow from the tip or apex of the plant. New cells are produced in these growing tips by meristems, groups of undifferentiated cells whose function is to divide by mitosis to produce new cells.Root growth begins at the root apical meristem (RAM). This meristem divides in two directions, producing a root cap to … WebJan 15, 2008 · Cell types or tissues in which regulation was observed are outlined in black (lateral root cap, endodermis/pericycle, stele) with pericycle founder cells highlighted (gray cells adjacent to black ovals representing xylem poles).

WebOct 21, 2024 · The LRs are derived from the pluripotent stem cells of the PR cambium, xylem parenchyma, and pericycle cells. ARs are differentiated from unipotent stem cells and existing stems, leaves, old roots, or hypocotyls, which are typically induced and activated by various stresses. They then undergo cell fate transitions from unipotent stem cells to ... WebParenchyma cells are dispersed throughout the vascular cylinder. The vascular cylinder of the root is surrounded by a layer of parenchymatous pericycle cells. As the root ages, many of these cells become fibres, particularly in monocotyledons and …
