For example, giberellins stimulate cell division in shoot apical meristem, causing the plant to grow taller. These hormones also cause cell elongation in intercalary meristem of grasses. Cytokinin and auxin are also important growth regulators.ateral meristem is called the vascular cambium in many of the plants in which it is found. Secondary growth gives a plant added stability that allows for the plant to grow taller. Lastly, some plants have intercalary meristem.
An apical meristem is of each root tip is a dividing zone that forms new cells in two directions. The meristem produces new cells in front of itself that become a loose fitting rootcap. Layers of cells in this cap are continually brushed off as the root elongates between soil particles.
