In this article we will discuss about the significance of root stem transition. During vascular transition there is a reorientation of primary xylem and primary phloem. The reorientation of primary vascular tissues commonly takes place in the hypocotyl of the embryo in provascular strands. Transition regions have their own specific orientation of vascular tissues. This orientation cannot be compared with [...]
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 [...]
In this article we will discuss about the interxylary periderm in plants, explained with the help of suitable diagrams. The periderm, which is formed in the wood and medullary tissues, is described as interxylary periderm. The formation of periderm at the periphery of stems and roots, and its protective function are generally recognized. But the periderm in the wood and [...]
