WitrynaThe Pericycle is the outermost layer of the stele and innermost layer to the endodermis which is made up of parenchymatous cells. Pericycle plays an important role in lateral root formation and secondary growth. Auxin and cytokinin plays an important role in root growth. Branch roots arise from primary meristematic tissues. Root hairs are short ... Witryna25 cze 2024 · Cambium cells promote new growth at lateral meristems, allowing plants to increase in girth or produce new branches.

The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues it surrounds. In eudicots, it also has the capacity to produce lateral roots. Branch roots arise from this primary
WitrynaThe occurrence of a meristematic phase of endodermis in Asteraceae was first demonstrated by Williams (1947). That author demonstrated that the cellular layer, which surrounds the plerome (pericycle), acts as a cambium generating the cortex, which later will differentiate into endodermis.
