WebShoot Meristems. The primary shoot meristem is a part of a complex organization of the shoot apex arranged in three zones (Figure 5B): (1) the central zone harbors slowly dividing stem cells at the summit and an organizing center beneath maintaining the stem cells, (2) all around is a ring-shaped peripheral region, where the daughter stem cells descended from … WebMay 4, 2024 · Plant stem cells are a small group of cells with a self-renewal capacity and serve as a steady supply of precursor cells to form new differentiated tissues and organs in plants. Root stem cells and shoot stem cells, which are located in the root apical meristem and in the shoot apical meristem, respectively, play a critical role in plant longitudinal …
WebJan 23, 2015 · INTRODUCTION. Shoot development is a plastic process that depends on the activity of pluripotent stem cells resident within the shoot apical meristem ().Differences in the initiation, determinacy, and size of different classes of meristems are responsible for variation in vegetative and reproductive architecture within the plant kingdom. Medullary tissue. There are two types of apical meristem tissue: shoot apical meristem ( SAM ), which gives rise to organs like the leaves and flowers, and root apical meristem ( RAM ), which provides the meristematic cells for future root growth. See more The meristem is a type of tissue found in plants. It consists of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells … See more Apical meristems may differentiate into three kinds of primary meristem: • Protoderm: lies around the outside of the stem and develops into the epidermis. • Procambium: lies just inside of the protoderm and develops into primary xylem and … See more Under appropriate conditions, each shoot meristem can develop into a complete, new plant or clone.
