Secondary Growth in Dicotyledonous Stems (With Diagram)! Introduction: The dicotyledonous stems show distinct secondary growth in thickness, as they usually possess collateral open vascular bundles. The cambium present in the bundle, otherwise known as a fascicular cambium, mainly produces secondary tissues at the initial stage. Normally a few methods of secondary increase have been found in the dicotyledonous stems. The [...]
The below mentioned article provides an outline of internal structure of stem of both dicotyledons and monocotyledons type. The embryo develops into a plant with root-stem axis and the appendages. In fact, three important organs of a plant are the stem, the leaves and the root. The continuity of the tissues, and particularly the vascular system, has been discussed in [...]
The below mentioned article will highlight the three types of modification of stem. They are: (1) Underground Modifications for Perennation, Vegetative Propagation and Storage (2) Sub Aerial Modifications for Vegetative Propagation and Perennation and (3) Aerial Modifications. A. Underground Modifications for Perennation, Vegetative Propagation and Storage: A number of herbaceous plants find it impossible to survive above ground during unfavourable [...]
