In this article we will discuss about the origin and activities of vascular cambium in plants. Origin of Vascular Cambium: In stems the vascular cambium and the primary vascular tissues differentiate from procambium. Procambium develops from the derivative cells of apical meristem. Transverse sections of a growing vegetative shoot apex reveal the presence of a cylinder of cells that are [...]
Vascular cambium occurs in the stele. The cells of cambium remain surrounding the primary xylem in both stems and roots. The vascular cambium is one cell thick permanent secondary meristem. It is often described as cylindrical and develops between primary xylem and-phloem. It is present in stems and roots and in their branches. It extends from tips to the bases [...]
The below mentioned article provides a short note on lianas. Liana (=liane) represents an ecologically specialized plant form. The plants are climbing and the specialized lianes have winding stems. It is regarded that winding is governed by light requirement. Lianes have stem that is much narrower than the length. The winding stems are strong and pliant. The vascular system of [...]
