Central cylinder
The central cylinder is a term from botany . It describes the central part of the root and the stem axis of vascular plants . The primary bark follows outwards . In the root, the pericambium (pericyclic) forms the outermost layer of the central cylinder and delimits it from the endodermis , the innermost cortical layer.
The central cylinder contains vascular bundles (the so-called stele ), the basic tissue ( medulla and medullary rays ) and, if necessary, strengthening tissue ( sclerenchyma ).
