Let us learn about Secondary Growth in Dicotyledonous Roots. After reading this article you will learn about: 1. Introduction to Secondary Growth 2. Formation of Cambium and Development of Secondary Tissues 3. Periderm. Introduction to Secondary Growth: The roots of gymnosperms and most dicotyledonous undergo secondary growth. Most of the dicotyledonous roots show secondary growth in thickness, similar to that [...]
Let us make in-depth study of the organ, mechanism, factors and methods of water absorption. Absorption of water and nutrient material is carried on only by the younger portions of a root, near its tip (See Fig. 2.2). The very tip itself is usually covered with a sheathing root cap of cells which protects the delicate underlying tissues as the [...]
Absorption of Water by Roots (With Diagram)! Now for the actual absorption of water by the roots—it can be shown that when a root hair is in contact with a number of cortical cells of the root and finally a trachea or a xylem vessel, water will enter the root hair, pass from there into the cortical cells and finally [...]
