In this article we will discuss about the stages of secondary growth in dicotyledonous root with the help of suitable diagrams. The roots of some herbaceous dicotyledons and of all gymnosperms and woody dicotyledons show secondary growth in thickness. The tissues of secondary origin in the dicotyledonous roots are basically similar to those of the stem, but the way of [...]
The upcoming discussion will update you about the difference between dicotyledonous root and monocotyledonous root. Difference # Dicotyledonous Root: 1. Epidermis is single layered. 2. Cortex is composed of parenchyma cells only. 3. Pericycle gives rise to a portion of vascular cambium that gives rise to secondary vascular tissues and phellogen—the meristem of cork. 4. Xylem is monarch to hexarch. [...]
The following points highlight the top eight anatomical characteristics of dicotyledonous roots. The characteristics are: 1. Xylem Bundles 2. Cambium 3. Pith 4. Epidermis 5. Cortex 6. Endodermis 7. Pericycle 8. The Vascular System. Dicotyledonous Roots: Anatomical Characteristic # 1. Xylem Bundles: The xylem bundles vary from two to six numbers, i.e., they may be diarch, triarch, tetrarch, pentarch or [...]
