In this article we will discuss about the two typical dicotyledonous plants which been selected for the study of internal structure of stem with the help of diagrams. 1. Young Sunflower Stems (Figs. 146 & 147): If a thin and uniform transverse section is taken from a young sunflower stem and observed under the microscope, the following plan in the [...]

In this article we will discuss about the secondary growth in dicot stem. A. In the Intra-Stelar Region: The secondary growth always begins in the intra-stelar region. The meristematic cells of the cambium of the vascular bundles, called fascicular cambium, begin to divide and produce new cells on the outer and inner sides. (Fig. 158) Almost simultaneously a few parenchymatous [...]
